WEST SEATTLE BRIDGE CLOSURE: What SDOT director, mayor, councilmember said during ‘town hall’

Though the announced-at-the-last-minute “West Seattle Town Hall” a few hours ago was not primarily about the bridge, that was a major topic, unsurprisingly. No new information, but SDOT director Sam Zimbabwe‘s part of the program offered some new framing of where things stand. We recorded video of the entire event, which we’ll publish in a separate report; here’s a clip with just his 10-minute segment:

We screengrabbed key slides to summarize his update. First, project priorities:

Then he went through a quick recap of the heart of the emergency plan whose key points were unveiled last week (WSB coverage here):

This next slide was the first time we’ve seen SDOT try to give a visual explanation of the dramatic loss in street capacity to and from West Seattle:

Then, what seemed tailored to those who are worried nothing’s being done:

This one, for those wondering why the bridge isn’t already being repaired or demolished:

And here’s another promise that they’re working on traffic management, with the stay-home order potentially lifting in less than three weeks:

Another slide along the way recapped how many meetings they’ve spoken at:

Earlier in the event, both Mayor Jenny Durkan and Councilmember Lisa Herbold included the bridge in their opening remarks. Durkan described the bridge as “a vital, vital piece of infrastructure … for our entire region.” She says she’s been discussing the situation with all levels of government – federal, state, county, regional. She also reaffirmed her support for current restrictions on the low bridge, saying it has its limit. But she promised the city will “do everything” it can “to increase mobility” (for West Seattle).

As she has before, Herbold declared the bridge closure a “crisis.” In counterpoint to the mayor, she said she will continue advocating for some changes in low-bridge restrictions, such as opening it to personal-car drivers during late-night/early-morning hours. (In subsequent Q&A, the mayor seemed to soften a bit on that, saying “all requests” would be considered.) Herbold also summarized recent developments such as the SFD announcement that another medic unit and ladder truck would be added to this side of the Duwamish River.

Again, we’ll recap the rest of the two-hour event – which featured more than half a dozen other city department heads – in a separate story.

FOLLOWUP: Roxbury repaving expected before month’s end

As reported here last Friday, Councilmember Lisa Herbold announced SDOT planned to repave two blocks of SW Roxbury, the badly rutted section between 16th SW and 18th SW. We subsequently asked SDOT about the timeline, and today the department confirmed the work will be done before the end of the month, and once it starts, will last up to a week. They also sent this flyer that will be mailed to nearby homes and businesses this week:

WEST SEATTLE BRIDGE CLOSURE: SDOT explains new monitoring system

One week after SDOT went public with some details of its emergency plan in case of West Seattle Bridge failure or imminent failure (WSB coverage here), it’s just published a close-up look at the new monitoring system. The graphic above is from the new SDOT Blog update, which also includes photos of some of the monitoring equipment. Also explained – the monitoring is also key to the biggest decision yet to be made. Three main purposes are listed:

*Keep us informed on how the bridge reacts to environmental changes, bridge stabilization measures, temporary shoring, and potential future repairs.

*Give us a better indication of bridge distress that could warn of impending failure.

*Guide us to a decision about the technical feasibility of repair or replacement.

SDOT says the system includes cameras, movement sensors, and crack monitors, noting:

The new intelligent monitoring system is already ‘talking’ to us and telling us that there is some potential for failure. What we don’t yet know is how great that potential is. The new system will help us better determine that.

SDOT adds that “after we collect a few weeks’ worth of data”:

Analytic modeling will interpret the data to gain a baseline understanding of the bridge’s behavior. If we observe stable behavior, the bridge will continue to be monitored during and after the temporary crack arrest measure installation and the Pier 18 restrained lateral bearings’ release, to see how the bridge reacts.

WEST SEATTLE BRIDGE CLOSURE: Many needs, one voice? District 1 Community Network discussion

By Tracy Record
West Seattle Blog editor

As city leaders make decisions about the West Seattle Bridge‘s future and the impacts of its long-term closure, who can/should speak for the peninsula?

That was a major topic at the May meeting of the District 1 Community Network, a coalition of West Seattle and South Park community advocates, with 30 people in attendance via videoconferencing/phone.

D1CN members weren’t suggesting their coalition should or could take on that role. But in the course of two hours’ discussion, an idea took shape:

WEST SEATTLE BRIDGE CLOSURE: 6 new traffic cameras

Just got word from SDOT today – they’ve added six new publicly viewable traffic cameras, on SW Roxbury and on 35th SW. We’ll be adding them to our traffic-cams page and weekday-morning traffic watch. From east to west and south to north, they are:

15th/Roxbury:

16th/Roxbury:

35th/Roxbury:

35th/Barton:

35th/Holden:

35th/Morgan:

Any more on the way? We’ve asked, and we’ll add the reply when we get it.

P.S. You also can find these cameras, and others around the city, via SDOT’s traffic-info map.

WEST SEATTLE BRIDGE CLOSURE: Extra SFD truck, medic unit on the way

(Seattle Fire Department photo of Ladder 13 in 2010)

Not long after the West Seattle Bridge‘s sudden shutdown, we and others started asking whether West Seattle would get additional SFD resources, as happened during the Spokane Street Viaduct Widening Project (east half of the bridge) in 2011-2012. The early answer was: It’s being discussed. New answer today: Yes. In addition to West Seattle-based Medic 32, SFD will station Medic 26, staffed with two paramedics, at Station 26 in South Park. And joining WS-based Ladder 11 will be an extra truck, Ladder 13, to be based at Station 37 in Sunrise Heights. The announcement says, “Beginning in June, these units will be in-service for responding to emergencies 24-hours per day, seven days a week.” (Ladder 13 was based at Station 11 in Highland Park during the SSV project.) The SFD announcement adds, “The new medic unit and ladder truck are coming from SFD’s reserve apparatus located at the City’s Fire Garage. The department will continue to have other apparatus on reserve to support scheduled maintenance and for any unforeseen mechanical issues. The funding required for staffing the two new units, apparatus maintenance and fuel, and room accommodations at the fire stations is approximately $2.5 million for the remainder of 2020 and will be covered from existing resources.”

FOLLOWUP: SDOT’s reply to HPAC’s 13 West Seattle Bridge closure-related requests, and more

(WSB photo from April, new signal at Highland Park Way/Holden)

HPAC the community council for Highland Park, Riverview, and South Delridge – got a fast reply from SDOT on its letter centered on 13 requests related to the West Seattle Bridge closure and its effects on those neighborhoods. We spotlighted the letter here on Tuesday; HPAC circulated the response tonight. It’s signed by Heather Marx, who’s leading the West Seattle High-Rise Bridge Safety Project. The letter, which you can see in its entirety on HPAC’s website, also incorporates topics from HPAC’s April meeting (WSB coverage here). From the response, here are HPAC’s points, and SDOT’s replies:

… Below are the specific requests we heard from HPAC – at both your meeting and in your letter – with the status of each request:

Highland Park Way SW and SW Holden St Intersection

*Request for a left-hand turn signal for turning onto SW Holden St from northbound lane on Highland Park Way SW
Status/update: We installed a temporary traffic signal at this intersection and it’s not currently possible to add a left-hand turn signal to it. We are, however, sharing this feedback with the team designing the permanent traffic signal scheduled to be installed in 2021.

*Request for extra traction on uphill southbound lane on Highland Park Way SW
Status/update: The Highland Park Way SW and SW Holden St Safety project team will evaluate high friction surface treatment. This treatment has typically been done where crashes have occurred when roadway conditions were slippery.

*Request for separate green signals for pedestrians and drivers in the northwest corner of the intersection
Status/update: We installed a temporary traffic signal at this intersection and it’s not currently possible to add these features to it. We are, however, sharing this feedback with the team designing the permanent traffic signal scheduled to be installed in 2021.

Turning from arterial streets onto SW Holden St

*Request to see painting and/or signage to prohibit blocking of the intersections
Status/update: Because these treatments have limited effectiveness and high maintenance costs, SDOT is focusing on more effective tools, many of which are below and will also be reflected in the neighborhood traffic plans we are preparing.

From West Seattle Bridge mini-update to ‘distracted-driving cameras’ @ Move Seattle Levy Oversight Commttee meeting

By Tracy Record
West Seattle Blog editor

Since a brief West Seattle Bridge update was on the agenda, we listened in on last night’s monthly meeting of the Levy to Move Seattle Oversight Committee.

That wasn’t the only item of interest, though – the meeting also touched on two curiosity-piquing potential future tools in the ongoing Vision Zero safety program, and an unsurprisingly dour budget update.

First, the bridge. While its emergency needs obviously aren’t part of the original plan for the levy that voters passed in 2015, which is what this all-volunteer advisory group monitors, SDOT put it on the group’s radar last month. So deputy director Lorelei Williams presented a short update last night.

WEST SEATTLE BRIDGE CLOSURE: 13 things HPAC says need to be done ASAP

With no detailed city plan yet for handling West Seattle Bridge-less mobility when the stay-home order lifts, local groups are continuing to spell out their proposals. Today, we hear from HPAC, the community council for the areas most affected by detoured traffic – Highland Park, Riverview, South Delridge. While SDOT guested at HPAC’s meeting April 22nd (WSB coverage here), they had no specifics beyond the Highland Park Way/Holden signal that was installed in the first week post-bridge closure. So HPAC has sent a letter (see it here in PDF) to the mayor, council, and SDOT, noting that “… we are now in week 7 of the closure and very few of the public concerns that have been raised have been adequately addressed.” HPAC has these 13 specific concerns/proposals:

… Issues and areas that need to be addressed before the stay-at-home order is lifted:

1. At the intersection of Highland Park Way SW and SW Holden St:

● A left-hand turn signal is needed for turning onto SW Holden from Highland Park Way/9th Ave SW northbound. Currently, traffic coming up the hill on Highland Park Way and going right does not stop, with SW Holden being so narrow, only one car being turning onto SW Holden, so traffic trying to turn left are stuck at the light for several cycles or cutting through SW Portland St at higher speeds.
● Extra traction on the uphill southbound lane on Highland Park Way.
● Separate green signals for pedestrians and drivers in the northwest corner of the intersection.

2. Traffic signal adjustments to address traffic backups at the following intersections:

● Add a left hand turn signal at 16th Ave SW and SW Holden St as previously requested for
over the last 6 years.
● Delridge Way SW and SW Holden St.
● Orchard St. and Delridge Way SW
● 8th St and SW Roxbury St.

3. Traffic calming features on our neighborhood streets:

● For the school zones of Chief Sealth HS, Roxhill Elementary, Sanislo Elementary and Highland Park Elementary.
● Police presence to curb excessive speeding on 16th Ave SW
● Signage at 4-way intersections to ease transit for vehicles, bikes and pedestrians. Signs
along SW Thistle St at 20th and 18th Ave. Stop sign at 11th and Kenyon St.
● Work with the neighborhoods to identify streets to become one-way to help mitigate cut- through traffic.

4. Turning onto SW Holden St from streets both east and west of Delridge Way is extremely difficult with increased traffic.

● Mitigation requested.

5. West Marginal Way S:

● Increase the number of lanes to get onto the on ramp for the 1st Ave bridge.
● Request for better bike lane marking at the intersection with Highland Park Way SW
● Request to fill potholes and fix road deterioration near the railroad tracks
● Request for two lanes northbound at the intersection with Highland Park Way SW

6. Pedestrian path on the east side of Highland Park Way after the SW Holden intersection:

● Request to consider widening the path to allow for more use
● Request to clean moss off from path

7. Left-hand turn signal requests at the following intersections:

● 16th Ave SW and SW Holden St
● 16th Ave SW and SW Roxbury St.
● 8th Ave SW and Roxbury St.

8. King County Metro Route 131

● Make a bus-only lane starting at SW Holden and Highland Park Way going on through to West Marginal Way then over the 1st Ave bridge toward Seattle.
● Request to adjust signal at Highland Park Way SW and SW Holden for bus priority
● Increase Route 131 service.

9. We want to clearly understand the traffic patterns throughout the peninsula. SDoT has never taken into consideration the east-west traffic flow throughout West Seattle. We want to know what routes people are taking and which streets are becoming major arterials. Monitoring should be placed at the following intersections:

● SW Orchard St. and SW 35th Ave
● SW Orchard St. and Delridge Way SW
● SW Holden St. and SW 35th Ave
● SW Holden St. and Delridge Way SW
● SW Thistle St. and California Ave SW
● SW Thistle St. and SW 35th Ave
● SW Thistle St. and Delridge Way SW
● SW Trenton St. and SW 35th Ave
● SW Trenton St. and Delridge Way SW
● SW Barton St. and SW 35th Ave
● SW Henderson St. and Delridge Way SW
● SW Henderson St. and 9th Ave SW
● SW Roxbury St. and 35th Ave SW
● SW Roxbury St. and Delridge Way SW
● SW Roxbury St. and 9th Ave SW
● Olson Pl SW and 1st Ave S

10. For the City of Seattle to increase Metro bus service for access for east and west transit on the peninsula itself i.e. access to California St./ Junction areas only offer the 128, which is hard for the rest of the peninsula to get to without using their cars.

● The transfers through the Westwood Village has been difficult for Highland Park riders since the reroute of the 136/137. Highland Park and Delridge Neighborhoods have been designated food deserts by the city.

11. A commitment from the City to repair the streets that were damaged during the bridge closure.

● Once traffic resumes we will have a better understanding of which of the streets that will be, but assume at least: Roxbury St, Delridge Way SW, SW 35th Ave, Highland Park Way SW, and Olson Way SW.

12. Heavy freight routes clearly designated and enforced.

● This type of vehicle will cause massive and immediate damage to our more residential
streets (i.e. Holden St) and will significantly slow traffic since these types of vehicles will
have issues turning the tight corners. Both Avalon St. and Roxbury with their wider lanes
and concrete enforced lanes are better suited for this type of transit.

13. We want an immediate bridge replacement plan without a $33 million expenditure for the current bridge or a two-year evaluation period. SDOT’s current plan will put an undue burden on the daily lives of our West Seattle residents.

Please learn from the I35 bridge failure and replacement in Minneapolis and the rapid rebuild of the Genoa, Italy bridge. No one waited for two years before making a decision on viability – just replace this bridge.

The $33 millioh reference, if you missed the original report, goes back to the April 15th briefing covered here – it’s the projected cost of stabilizing the bridge, planning traffic control, and doing maintenance on the low bridge.

WEST SEATTLE BRIDGE CLOSURE: 3-scenario emergency plan finalized

(WSB photo from April)

By Tracy Record
West Seattle Blog editor

While the city’s been working toward stabilizing the West Seattle Bridge and determining whether it can be repaired, they’ve also been working on an emergency-response plan in case the bridge was deemed at imminent or near-imminent risk of collapse – which currently, they stress, it is NOT.

Most of this has been taking place out of the public eye, with the city working with “stakeholders” who have operations close to the bridge, such as the Port of Seattle. This came up during last week’s inaugural meeting of the community coalition West Seattle Bridge Now (WSB coverage here), when a port rep noted that this emergency plan was front and center right now. We’ve been pursuing more information from SDOT, and today they are announcing key points of the plan.

SDOT stresses that the bridge is “stable” and that the cracks’ growth has “slowed” since the bridge was closed to traffic March 23rd. But “out of an abundance of caution” they’ve devised this plan for how they would get the word out, and what people would need to do, if bridge failure seemed likely before stabilization work is complete.

What they’re releasing today is what SDOT communications director Michael Harold explained to us in an interview this morning is the “essence” of the emergency plan; the plan itself will be released “soon.” Today’s announcement first notes:

We’ve established an interagency task force to coordinate a unified emergency response if conditions of the high bridge reach critical thresholds.

The task force includes the City of Seattle, King County, Washington State, Port of Seattle, Northwest Seaport Alliance, United States Coast Guard (USCG), and the US Army Corps of Engineers.

If we must activate the task force’s unified emergency response, a unified command will be led by the Seattle Fire Department (SFD), the Seattle Department of Transportation (SDOT), the Seattle Police Department (SPD), and USCG.

These and other agencies will work together to prioritize public safety and provide clear communication. SDOT will manage traffic operations to assist emergency response and provide consistent updates to the public. SFD will manage evacuation and, if necessary, rescue of people near the bridge. SPD will manage traffic control and assist with evacuation. USCG will manage maritime coordination and communication. Seattle Public Utilities and Seattle City Light will manage utilities to reduce impact on customers.

SDOT stresses that the “only section of the West Seattle High-Rise Bridge that currently has cracks is the highest span directly over the Duwamish River between West Seattle and Harbor Island. … The rest of the bridge is relatively stable and doesn’t currently show signs of distress.”

But just in case, the emergency plan addresses three potential scenarios:

1) Immediate evacuation to be used if the daily in-person inspections indicates enough of a change to warrant the immediate evacuation of a small number of properties, though we could
have hours or days before actual bridge failure.

2) One to five days notice to be used if the new remote monitoring instrumentation, which will be fully functioning in mid May, indicates enough of a change to warrant execution of evacuation plans within one to five days. If failure is anticipated, but not immediate, SFD and SPD will clearly communicate, via direct site visits and other platforms, when evacuation must occur.

3) Controlled demolition to be used if the change in the condition of the high bridge indicates the need for execution of an evacuation plan followed by a controlled demolition.

The #1 response would involve evacuations in what’s considered “the Fall Zone.”

In what Harold calls a “very conservative estimate,” this area was identified via “modeling potential cracking scenarios” plus adding a buffer zone – it’s an area “225’ north and south of the bridge, 225’ west of Pier 15, and 225’ east of Pier 18, and includes the Spokane Street Low Bridge, parts of Harbor Island, the Duwamish Waterway, and areas on and around West Marginal Way.” (This is the type of information that the “critical failure modeling” mentioned in Councilmember Lisa Herbold‘s update last Friday is addressing – not an estimate of when a failure could happen, but of how it might happen, IF it happened.)

Even if they don’t have to evacuate, some on Harbor Island could see travel affected, so: “It is recommended that people on Harbor Island who are non-essential leave the island using the eastern approaches if they receive any notification that the West Seattle High-Rise Bridge is at risk. Those staying should know that emergency response could potentially block vehicle access to the island.” (added 2:07 pm – traffic map)

The Fall Zone does NOT include any residential areas, not even Pigeon Point adjacent to the bridge, SDOT says. But SFD and SPD would close access to nearby roads.

A mailer is being sent later this week to all addresses within a quarter-mile of the “fall zone,” Harold says. But in the meantime, even if you’re NOT that close, everyone in West Seattle is urged to sign up for Alert Seattle – an opt-in service through which emergency messages are sent and one way through which the city will send any bridge-related emergency notification.

Today’s announcement also says any bridge-related emergency alert will also be sent through “Wireless Emergency Alert (WEA) text messages … an alert system that sends text messages to all cell phones within a particular area. This is the same service that sends Amber Alerts. WEA will send text message alerts to all cell phones in the impacted area at the time of alert.” The Coast Guard also would send “an Urgent Marine Information Broadcast over VHF Channel 16 to warn mariners to avoid the Duwamish Waterway,
and they will use the USCG Alert Warning System to warn commercial operators and terminals on Harbor Island and the Duwamish Waterway.” Along with all those alerts, SDOT would also notify the media and publish warnings via its social-media channels.

But, Harold stresses yet again, they do NOT believe there is a risk of the bridge collapsing any time soon – they nonetheless have to be prepared. They’ve been installing instrumentation to enable real-time monitoring of the bridge status – in addition to continuing “near daily” inspections. We’ve asked how exactly that monitoring is being monitored, so to speak; Harold says they’ll be releasing those details this week too.

Questions? He says SDOT is ready to answer them via email or phone any time, 684-Road@seattle.gov or
206.684.ROAD (206-684-7623). Meantime, you also can find released-so-far info via the bridge-project website, where documents and information links are already archived.

WEST SEATTLE BRIDGE CLOSURE: Bicycle groups’ suggestions for ‘strategies and actions’

While we await a plan for how to move people from and to West Seattle without the high bridge when the stay-home order ends, we’re continuing to spotlight feedback that various groups are providing to SDOT. Tonight – here’s what bicycling-safety groups are suggesting for “strategies and actions to help mitigate the closure of the West Seattle high-rise bridge. This letter was shared with us this past week by Don Brubeck, president of longtime community group West Seattle Bike Connections, which along with three other groups sent it to SDOT:

You can also read the letter here (PDF). Previously, we’ve featured letters from a coalition of South Park/Duwamish Valley groups (here) and from the West Seattle Transportation Coalition (here).

WEST SEATTLE BRIDGE CLOSURE: 4 updates from Councilmember Herbold’s newsletter

(Photo by Jim Edwards)

Four more West Seattle Bridge updates tonight, this time from West Seattle/South Park City Councilmember Lisa Herbold. They’re in her weekly newsletter (which is also online here); she begins with the stabilization-contractor announcement, reported here last night, and continues:

Bridge Monitoring

SDOT’s instrumentation consultant, BDI, measured crack depths on the sides of the box girders where they meet the deck and also used ultra-sonic pulse echo imaging and ground penetrating radar to help in understanding if there is any weakness in the steel rope that holds the bridge in compression.

On April 22, SDOT’s design consultant, WSP, provided an estimate of rate of crack growth as well as a critical failure projection. WSP also continues work on a decision tree to inform the question of whether or not to replace or repair the bridge.

SDOT also is installing additional structural health instrumentation (such as crack-width gauges, strain gauges and high-resolution cameras). This is mostly complete and will allow for a clearer definition of the condition of the bridge, and which path to pursue.

I’ve asked how the rate of crack growth informs the question of whether or not to replace or repair the bridge, and about the critical failure projection.

Road/Traffic Update

SDOT paved and reconfigured the 5-way intersection below the West Seattle Bridge last weekend; average daily traffic on the low bridge is down to 6,480 vehicles per day, approximately the same as the baseline. Here is the most recent traffic data we’ve received, with West Marginal and Idaho, and Highland Park and Marginal showing significantly higher than usual volumes:

SDOT has installed new controllers, added communications to signals, and tweaked signal timing in both the Roxbury and 35th corridors, and has upgraded these intersections over the past two weeks:

Chelan 5-Way Intersection
17th Ave SW & SW Roxbury St
16th Ave SW/Delridge & SW Roxbury St
15th Ave SW & SW Roxbury St
35th Ave SW & SW Thistle St

SDOT also noted they are planning to improve operations at the following intersections over the next few weeks:

30th Ave SW & SW Roxbury St
26th Ave SW & SW Roxbury St
20th Ave SW & SW Roxbury St
8th Ave SW & SW Roxbury St
35th Ave SW & SW Roxbury St
35th Ave SW & SW Barton St
35th Ave SW & SW Henderson St
35th Ave SW & SW Trenton St
16th Ave SW & SW Austin St
16th Ave SW & SW Holden St
35th Ave SW & SW Kenyon St
35th Ave SW & SW Holden St
35th Ave SW & SW Webster St
35th Ave SW & SW Myrtle St
35th Ave SW & SW Holly St
35th Ave SW & SW Morgan St
35th Ave SW & SW Raymond St
35th Ave SW & SW Findlay St

Changes include allowing SDOT to manage signals from a central location, rather than needing to go to the signal to manually make changes.

Town Hall Question Totals

For the Town Hall held last week, over 1000 questions and comments were submitted: 133 on the use of the lower bridge, 156 on traffic management, 212 on transit (including ferries), 63 on whether to repair or replace, 209 on process and oversight, and 254 on multiple subjects, or other items. My office is continuing to organize the suggestions.

Letter to Washington State Ferries

I sent a letter to Washington State Ferries, linked here, asking that they consider re-directing some of the ferry traffic from Vashon and/or Southworth, that usually travels to the Fauntleroy ferry dock, to Downtown Seattle instead; and that they consider trips from Fauntleroy to Downtown, and options suggested by the public.

The letter notes that during some previous years, for example 1981, 1993 and 2002, eastbound ferry traffic has been diverted to Downtown on a temporary basis. Thanks to the community members who assisted with this research.

SDOT info, meantime, is on the West Seattle High-Rise Bridge Safety Project website; our coverage since the bridge closure March 23rd is all archived here.

WEST SEATTLE BRIDGE: Stabilization contractor announced

6:49 PM: Just announced by SDOT:

Seattle Department of Transportation (SDOT) is moving forward with West Seattle High-Rise Bridge stabilization. The City used emergency contracting authority to move with urgency in selecting a construction contractor to carry out Phase 1 stabilization work. Kraemer North America has been selected for Phase 1 construction and work is already underway.

There are three phases of repair for the West Seattle High-Rise Bridge:

Phase 1: Stabilization – The first step in stabilizing the bridge was to remove traffic from the High-Rise bridge on March 23. The second step is to repair lateral bearings on Pier 18.

Phase 2: Shoring – In Phase 2 we will add temporary external structures called shoring. Shoring is necessary to help support the bridge as we continue to assess repair feasibility, timeline, and costs.

Phase 3: Long-term repair – We do not yet know if repair of the bridge is feasible technically or financially. In the meantime, it’s critical that we carry out stabilization and shoring work to protect public safety.

Earlier this month we sent out a Request for Information (RFI) to determine who we would contract with to begin Phase 1 stabilization work on the West Seattle High-Rise Bridge, as quickly as possible.

Though this emergency situation authorized SDOT to waive all competitive bidding requirements (pursuant to RCW 39.04.280). On April 13, the City contacted six contractors and requested information on capacity, availability, resumes for key personnel, and approach. Four contractors provided the requested information by April 15, and our Capital Projects and Roadway Structures divisions evaluated and rated the submittals while also taking into consideration the City’s previous experience with the contractors and other factors.

This process selected Kraemer to fulfill the needs of the project.

Kraemer is a 109-year-old, engineering-minded, construction-focused contractor with a foundation in complicated structure work. The team’s construction experience directly relates to the High-Rise Bridge’s repairs.

Kraemer is an industry leader in segmental bridge repair and construction, as well as in concrete post-tensioning. This expertise will allow the team to carry out key stabilization activities, help in forensic investigation of the bridge, provide the engineering team with construction input to determine the best approach to stabilization, and confirm repair estimates.

With recent work on WSDOT’s Duwamish River Bridges Project, Kraemer also comes with a detailed understanding of the immediate vicinity, as well as knowledge of US Coast Guard permitting requirements. This is essential because obtaining these permits – or not – could add or subtract months to any stabilization, shoring, repair, or replacement efforts.

Kraemer’s northwest headquarters are located here in Seattle, with a committed, locally experienced team.

With a current contract to construct the new Northgate Bike and Pedestrian Bridge, which broke ground earlier this year, Kraemer understands the complexities of working in and around the City of Seattle. Finally, Kraemer has also worked closely with WSP, our bridge consultant. This relationship, which allows for a quick team integration and efficient approach to the work, will be essential as we move forward with stabilization work.

Kraemer is excited to help the people of West Seattle and others who rely on this critical infrastructure by delivering stabilization, shoring, and repairs quickly and safely.

Kraemer will provide the construction for Phase 1 stabilization work.  

They will conduct repairs designed to stop further cracking in the bridge’s most vulnerable sections.
They will then replace the lateral bearings on Pier 18 at the east end of the bridge. These bearings, when working correctly, allow the bridge to expand and contract with temperature change.

They will work with SDOT and the engineering consultant team to develop and finalize strengthening solutions for the bridge.
Kraemer’s first priority is to provide a constructability review of the West Seattle High-Rise Bridge stabilization designs.

A “constructability review” is critical to getting a construction project off the ground quickly and performing work safely. The contractor reviews the designs produced by the engineers to determine how easily it can be built and to provide input. In addition, the project leads at Kraemer are starting to develop plans for construction, health and safety, equipment and material procurement, work timelines and schedules, and permitting.

The bridge has been closed since March 23. We’ll be following up on questions not answered in the announcement such as projected cost/timeline.

9:55 PM: Here’s the work Kraemer is doing on the Duwamish River Bridges (the two spans that comprise what’s more commonly known as the 1st Avenue S. Bridge).

WEST SEATTLE BRIDGE NOW: New coalition launched ‘to convey urgency’

(WSB photo from earlier this month)

By Tracy Record
West Seattle Blog editor

A new community “coalition to convey urgency” about the West Seattle Bridge closure has just launched.

We were invited to cover the first meeting last night of people participating in West Seattle Bridge Now.

The online meeting was coordinated by community advocate West Seattle Realty (WSB sponsor) co-owner Kevin Broveleit, who opened with the declaration of what the group says tens of thousands of people know here, but others around the city and region need to realize too: “Losing the bridge is a catastrophic event.” So far, he said, most of what’s been heard from SDOT is “it’s not our fault” and “trust us, we’re doing everything we can … and nether resonate with us.”

So in the spirit of community groups that pushed for action to get the now-compromised bridge built in the first place, this one is determined to turn up the pressure and push for “action, not blame” by creating “as broad a coalition as possible” and focusing on “creativity in potential solutions.”

Those already involved who were part of last night’s meeting included a who’s-who of local community and business advocates. While there was spirited discussion about all three major needs created by the sudden shutdown of the bridge March 23rd, two of them – traffic mitigation and accountability – are not the central purpose for West Seattle Bridge Now, according to Broveleit. “The sooner we have a soluton with any sort of certainty,” the less painful it will be. Right now, he observed, his industry and others are grappling with people wracked by fear of the unknown – will West Seattle be bridgeless for more than the near-two-year minimum of which SDOT has already warned?

WEST SEATTLE BRIDGE CLOSURE: How it’s affecting South Park

(WSB photo: South Park Bridge just before its June 2014 opening)

The West Seattle Bridge closure isn’t just a West Seattle problem. That point’s been made far and wide already, but you probably haven’t heard it yet from this viewpoint – that of your neighbors in South Park, whose bridge (just six years old) is now one of two main alternatives for crossing the Duwamish River. The already-increased traffic has led to this letter to the city from a coalition of South Park community organizations, which we’re publishing with permission:

Dear Mayor Durkan, Councilmember Herbold & Director Zimbabwe,

The community of South Park is extremely concerned about the long term or permanent closure of the West Seattle Bridge and the potential for the lower Spokane St. bridge to also be shut down. We recognize that this closure will impact neighborhoods across West Seattle and within the Duwamish Valley. Our neighborhood is being promoted as a detour for the 100,000 drivers seeking an alternate route. During this time of reduced traffic, we are already seeing an increase in vehicle traffic, speeding and neighborhood cut-throughs. Residents of South Park have extremely poor health outcomes when compared to other neighborhoods. Our neighbors and children have high rates of asthma which has proven to reduce our life expectancy. Years of increased traffic will only perpetuate this inequity. We live in a valley that naturally traps pollution. Everything must be done to prevent additional pollution from coming here. Historically, our community has been disenfranchised and underserved by City and County services. We must have a voice in developing solutions to this long-term problem.

Our community members have raised the following concerns:

● Speeding and increased traffic in the neighborhood (Cloverdale, 14th & Dallas Ave S.)

○ Concerns about the safety of children crossing Cloverdale to get to school, the library, the community center etc.

○ Concerns about vehicles “whipping” onto Dallas Ave S. after crossing the bridge endangering pedestrians and cyclists (Dallas leads to the Duwamish Trail – a safe cycling route to downtown).

○ The increasing traffic back-up at the intersection of 5th & Cloverdale
● Increased pollution due to the increase in traffic
● The need to mitigate the impact on the already slow and often delayed 132 & 60 bus service

We would like to put forth the following recommendations:

● Transfer car trips from the West Seattle Bridge to transit, bike and walking trips to reduce pollution.

● Increase access to bus service. If West Seattle buses are rerouted to the First Ave or South Park bridges, some portion need to stop in South Park to provide us with better, faster bus service if we are to bear the brunt of the impacts of additional buses here. We also recommend the use of electric busses to reduce pollution.

● Safe pedestrian crossings
○ Lights for crossing at 10 or 12th & Cloverdale.
■ High-density new construction coming online in 2020 will bring even more neighbors to this area.

○ A light or highly visible crosswalk where Dallas Ave S. and the bridge meet to increase safety for pedestrians and cyclists.

○ A light or four-way stop on Dallas Ave S. near RAM Mounts at Thistle/Dallas/12th streets. Traffic cutting through the industrial area from Marginal Way has led to cars speeding down a residential street that already has a dangerous 4-way stop. We appreciate the Your Voice Your Choice intervention at this intersection, but it will not be enough to prevent accidents with increased traffic.

○ Crossing guards at 8th & 7th & Cloverdale for school children.
○ Improvements at 14th & Henderson.
● Improved Bike Connections
○ Protected bike lanes on the 1st Ave to downtown corridor are especially essential if the low bridge closure were to cut off access from the Duwamish Trail to downtown. A protected crossing across East Marginal from (and to) the First Ave Bridge is immediately needed for this bike route. More people will be biking and this connection is crucial.

○ Continue the funding, planning, and development of the Georgetown – South Park trail project
● Detours should keep traffic on major thoroughfares
○ Police should do consistent traffic stops to address speeding

We look forward to collaborating with SDOT and our West Seattle and Duwamish Valley community to develop solutions to this crisis.

FOLLOWUP: 5-way intersection repaving done

Thanks to Jim Edwards for the photo – that’s how the 5-way intersection (Spokane/Chelan/West Marginal/Delridge) west of the low bridge looked this morning after the second night of repaving. It’s since been striped, and here’s the SDOT cam view of how it looks now:

Lane reconfiguration and signal work was part of the projet too – here’s the SDOT one-sheet (PDF) explainng.

West Seattle Transportation Coalition talks bridge-closure ‘mitigation’ with SDOT and Metro

By Tracy Record
West Seattle Blog editor

Exactly one month after the West Seattle Bridge‘s sudden closure, the West Seattle Transportation Coalition hosted this week’s third community meeting about its effects.

Guests at Thursday night’s online WSTC meeting included Heather Marx and Adiam Emery from SDOT and Chris Arkills and Bill Bryant from Metro. As WSTC chair Michael Taylor-Judd reiterated at the meeting’s start, the focus was on “transportation mitigation” – how is everyone who drove across the high bridge going to get around now?

Marx opened by acknowledging that as a West Seattleite who was also surprised to hear about the bridge, “whatever you’re feeling, I’m feeling too.” She explained that she’s heading the project group – engineering, communications, etc., so if you’re looking for a point person, “I’m the one.” She went through the same slide deck as Wednesday night’s meetings (which in turn was mostly the same as Monday’s City Council briefing and last week’s “might not be fixable” media briefing), including a pitch for signing up for Alert Seattle “because the worst COULD happen.” (Not just bridge-wise.) She also acknowledged the letter SDOT had received from WSTC, and had new slides pointing out actions taken – or planned -from WSTC suggestions. They included:

WEST SEATTLE BRIDGE CLOSURE: Work this weekend includes 5-way repaving + lane reconfiguration including Delridge Way

This was not discussed in detail during either of tonight’s West Seattle Bridge-focused meetings, but details are in for this weekend’s paving work (first mentioned here last week) on the 5-way intersection east of the low bridge, and it will include some lane reconfiguration too – plus a new bus lane for the north end of Delridge. From SDOT Blog:

… Our traffic engineers are evaluating intersections and arterial roads to determine where improvements are needed to support people and businesses in West Seattle during the bridge closure.

This weekend we will repave and change the lane design at the 5-legged intersection of Delridge Way SW, Chelan Ave SW, and W Marginal Way SW, just west of the Spokane Street/Low Bridge.

Construction and lane design changes are a preemptive step to ensure pavement can withstand increased traffic and to keep transit, freight, and emergency vehicles moving.

The signals at this intersection were upgraded on April 1 to allow us to control the signal remotely from our Traffic Operations Center. We can monitor and make real-time adjustments to the signal operations in response to changing circumstances.

WHAT TO EXPECT

The intersection will remain open during the day on Saturday, however there may be some disruption on Sunday.

We’ll grind the top 2 inches of the existing asphalt, repave, and restripe the intersection. Work is weather dependent. Should construction take longer than anticipated, work will happen on future weekends and notification provided in advance. Our objective is to complete work before Governor Inslee’s “Stay Home, Stay Healthy” order is currently scheduled to end, May 5.

Neighbors can expect noise from heavy equipment and activities, including asphalt removal and asphalt placement during the night.

Signed detours and uniformed police officers will be in place to help people navigate the intersection.

If people are biking in the street, they will have to follow vehicles through the detour. If they are on the sidewalk or shared trail, they will be treated like pedestrians at the intersections and crosswalks

WORK SCHEDULE

Intersection construction will occur overnight between the hours of 7 PM, Friday, April 24 and 7 AM, Saturday, April 25 and again from 7 PM, Saturday, April 25 and 7 AM, Sunday, April 26.

The intersection will be open to traffic during the day; however, there may be some disruptions on Sunday, April 26, related to striping and signal outages. If this occurs, signed detours will be in place as well as unformed police officers.

The new Delridge Way SW northbound bus lane will be installed from 9 AM to 5 PM, Saturday, April 25.

The Spokane Low Bridge will be intermittently closed from 8 AM-12 PM on Saturday for all vehicles; and from 12 PM-5 PM for people walking and biking for live load testing. Closures will be approximately 10 minutes in length, about the time for a normal opening.

NEW LANE DESIGN

To support bus service, emergency response, and freight movement over the Spokane Street Low Bridge the following changes are happening:

Delridge Way SW will get a bus-only lane northbound from SW Andover St to Chelan Ave SW.

The east leg of the intersection (westbound W Marginal Way SW) is going from 2 through lanes to 1 through lane and 1 left-turn lane.

The west leg of the intersection (Chelan Ave SW) is being converted from 1 shared left and through lane to 1 through lane 1 left-turn lane.

Here’s the construction info sheet (PDF) for this work.

WEST SEATTLE BRIDGE CLOSURE: HPAC talks traffic with SDOT

Shortly after the town-hall meeting about the West Seattle Bridge closure, HPAC – the community council for Highland Park, Riverview, and South Delridge – met online with SDOT reps to talk about traffic effects. SDOT reps included Heather Marx and James Le (who was managing the Highland Park Traffic Safety Improvements Project even before the bridge closure).

Shortly after the bridge was shut down, the neighborhood got a rush-installed traffic signal at Highland Park Way/Holden, the intersection where HPAC and other community advocatess had fought for improvements for decades. But nothing of major note has followed.

HPAC was hoping to hear a plan from SDOT – but the hour-long meeting was more about participants offering questions/concerns, and SDOT listening. One voiced frustration that, a month into the closure, there wasn’t more of a traffic-action plan yet. Here’s how the meeting went:

VIDEO: West Seattle Bridge Town Hall – 1,000 questions, 24 answers

(View the archived video starting 59 minutes into the clip)

5 PM: One month ago tomorrow, the West Seattle Bridge was suddenly shut down for safety concerns. One week ago today, SDOT announced the bridge will be out of service at least until 2022, and may not be fixable. Tonight, City Councilmembers Lisa Herbold (who represents West Seattle) and Alex Pedersen (who chairs the Transportation Commiitee) are leading a town-hall meeting about the situation; SDOT’s Sam Zimbabwe and Heather Marx are expected to join them, with Seattle Channel’s Brian Callanan moderating. (Datapoint: Everyone mentioned above, except Pedersen, is a West Seattleite.) If you’re among the 3,000+ people who RSVP’d, you should have received a link for questions. We’ll be covering this as it happens, ahead.

Format as announced: Presentation until 5:45, then Q&A. In opening remarks, Herbold promises to work to ensure that SDOT takes constituents’ suggestions seriously, including traffic and oversight as well as about the bridge itself. She says 300 questions have been received already. Pedersen pledges to work closely to “expedite plans for next steps.” Then it’s on to Zimbabwe. Notation on the slide deck indicates it’s the same one from Monday’s City Council briefing, so we’re featuring that below:

Zimbabwe recaps the bridge history and why it was closed, and reiterates that they don’t believe the bridge is in “imminent” danger of collapse. He does, however, advise people to sign up for Alert Seattle just in case.

5:16 PM: Just noticed a change in the slide deck – more details on the cracking right before the bridge’s abrupt closure. “Four feet of growth in two weeks.” Will add screengrabs.

Otherwise, it’s recapping what was explained at the last two briefings (this past Monday and last Wednesday), and what happens next – the Pier 18 repairs, the shoring to stabilize the bridge, the determination of whether the bridge can be fixed.

5:25 PM: Marx now takes over to talk about what’s being done regarding traffic. She first recaps the low-bridge restrictions, and also mentions again that repaving is scheduled this Friday-Sunday for the Chelan/Spokane/Delridge/West Marginal “5-way” intersection at the low bridge’s west end.

New: A “what can you do” slide that pitches SDOT’s various communication channels (here’s the bridge-project website, which includes the email subscription link mentioned). She urges people to start planning for post-stay-home, and to follow the low-bridge restrictions.

5:35 PM: The Q&A begins. Callanan thanks the 3,300 who RSVP’d and 1,800 who are watching the stream. First Q: “Why not proceed immediately with demolition and rebuilding?” Zimbabwe: “We’re working to get the information we need to make that decision … the cost of immediately proceeding to replacement would be (a lot) …we have to stabilize the bridge to maintain public safety. While we (do that), we’re (looking at) those types of questions.”

Q: Is Seattle working with King County to increase water taxi service? Herbold starts the reply: “I’ve had some initial conversations with County Councilmember Joe McDermott” and says she’s talked with State Sen. Joe Nguyen and some port commissioners about the suggestions of involving car-ferry service too. Marx says they’re working with Metro re: buses and Water Taxi for a “full suite” of options. Zimbabwe says he has spoken with WSF and other transportation agencies, all of whom are willing to “roll up their sleves to help.” Despite known constraints, “nobody’s saying no” to any idea, so far, he adds.

Q: What about combining a new bridge with the light rail bridge (that is going to have to be built anyway)? “Nothing is off the table,” replies Zimbabwe, noting that Sound Transit’s light-rail EIS is due next year, but also noting that ST’s construction schedule is not set to start until 2025. Herbold adds that “if we want ST to consider a multimodal bridge in its EIS, the ST board would have to” order that change in their studies, so they’re working on what it would take to make that happen. “It’s possible a bridge could be operational before” the light rail.

Q: Medical worker says his commute’s become a nightmare. What’s being done to help alleviate that? Marx replies that “we will continue to work closely with Metro to ensure transit is robust and available” but reiterates that they can’t add more users to the low bridge because it will quickly become “overwhelmed.” She adds that when SPD isn’t there to enforce, people break the rules and it “creates a really dangerous situation.” What about off-peak? They don’t have enough data yet to know if that’s feasible.

5:46 PM: Q: Were the people who built the bridge available to consult on a solution? Zimbabwe mentions the plan for a Technical Advisory Panel (those slides were not recapped in this presentation). He says that 35+ years have elapsed since it was built so they’re talking to a wide variety of outside experts. “This is a complicated structure, it’s going to be complicated to repair …”

Q: Will private employee shuttles be allowed to use the low bridge? Herbold says she’s been fielding that already – Amazon, for example, had four roundtrips daily. Marx said right now, no, but they’ll continue to “talk with those larger companies. (but) the answers … might be different” post-COVID. (A few minutes later, Zimbabwe explained that they’re monitoring traffic on the alternate routes.)

Q: What is being done for bike routes if the low bridge has to be closed? Are other routes going to be improved? Marx says those are longer-range plans. Herbold mentions the East Marginal Way safety project and says they’re looking at whether any of it could be accelerated.

Q: Could a toll be used to pay for a new bridge? Zimbabwe repeats that “nothing’s off the table” but tolls are complicated but that hasn’t been discussed in any detail. Herbold says she’s meeting later this week with U.S. Rep.. Pramila Jayapal (also a West Seattleite by the way) to talk about federal funding options.

Callanan notes at that point that they’re up to 600 questions.

Q: Just bought a house in West Seattle. How will this affect property values/taxes? Herbold notes the County Assessor is accountable for that but “there may be an opportunity to make that request” as well as an appeal process. Zimbabwe says a few minutes later that they’re working “tirelessly” to restore the traffic capability.

Q: What’s the plan to manage the increase in traffic along Roxbury/Olson, and on Michigan leading to I-5? Marx repeats, “It’s really not an option for everybody who used their car to get to and from West Seattle” to continue to do that – can you do what you can “to lighten the load on the system? … No amount of spot improvements will replace the high bridge.”

6 PM: Q: No hospital in West Seattle – address that. Herbold says the West Seattle Junction Association is working with a health-care provider to see if they might locate “a small hospital” in The Junction. Marx says the lack of a hospital is another reason why keeping the low bridge open for emergency traffic is vital. But she also reminds people that Highline Medical Center is available, to the south.

Q: Why if the cracks were first noted in 2013 was nothing done, or at least, with worsening cracks noticed last year? Zimbabwe repeats that they were not proceeding in a major way for a long time and they were indeed “modeling” and doing some repairs – epoxy – the acceleration happened. He repeats that the acceleration happened “very very quickly.”

Q: Has there been any discussion with Army Corps of Engineers about building a temporary bridge across the Duwamish River? Zimbabwe says the waterway has to remain open to navigation but they’ll “look at every option to accelerate” and “will look at every one of those possibilities.”

Q: Can some RapidRide C buses continue on to Ballard? SDOT is “open” to ideas and working with Metro.

Regarding traffic on neighborhood streets, Marx mentions the lower-speed-limit signs ae being installed along the detour routes. (We had been waiting for a response on SDOT after several people mentioned the sign installation.) She urges people to respect the neighborhoods they’re driving through.

Q: Can the high bridge withstand a moderate earthquake? Zimbabwe says they’re concerned about its stability in normal conditions, so …

Q: Callanan follows up with a question about the condition of the 1st Ave.S. Bridge. It’s newer, Zimbabwe points out. (Editor’s note: We’re working on a story about that – it’s partly newer, one side is from the mid-’90s, one side dates back to the ’50s.)

Q: Can low-bridge maritime openings be halted during commute hours? Marx: No, but the Coast Guard has published a notice asking mariners not to request opening in those times “and we’ve had pretty good luck with that.” Herbold says she understands something “stronger” has been requested, as was used during three weeks of “Squeeze.’ Marx says yes, they have, but they need to do “some significant outreach to the maritime community” to talk about that but emergency-response plans (in case of a high-bridge failure risk) is what they are mostly working on now “with that community.”

Q: What about a bike-to-car space by the low bridge? Marx says they’re looking at that too but they really are stressing, try transit.

Q: Can Roxbury be striped to 4 lanes and create an HOV lane? Zimbabwe says they’re “open to all sorts of ideas.” He notes that they don’t want to “walk back” on Vision Zero safety projects (of which that was one). Herbold says she hears a lot about Roxbury and that her office is compiling detour-route traffic ideas and hopes to map those and break the peninsula into sections to tour detour routes and make specific suggestions. “I just want folks to know how we’re using the information you’re sending me.”

Q: Husband of an expectant mom who will need to get from Alki to First Hill wants to know if they’ll have to use the 1st Ave. S. Bridge. Marx says she can’t imagine a police officer not letting you through. “If your wife is in labor, feel free to use the low bridge.”

Q: The pile-driving question, as answered here previously. No, the work at Terminal 5 is not believed to be a factor – there was no damage to anything even much closer to the project. Herbold says she’s asked port and SDOT to talk about the pile-driving that will resume soon so she wants to be extra-sure it won’t affect the high bridge.

Q: What is a ballpark time range for how long it would take to replace the bridge if that were the only option? Zimbabwe says he thinks about that option but “we just don’t know.” He acknowledges some bridges elsewhere have been rebuilt quickly, but many factors would be involved here. “We don’t know if we could reuse the foundations, what permits (we would need) … I urge people to go out and see how when the low bridge opens, it opens very very close to the high bridge.” Overall, “We hope to answer that as soon as we can.”

Callanan says they’ve now received 1,000+ questions – many he asked were attributed to multiple people – and that council staff will work on the ones that didn’t get answered. At 6:30 sharp, the event ends. It should be re-viewable above soon; we also recorded off the screen so we’ll have it later tonight if the official archive lags.

6:59 PM: We just checked – you can now watch the archived video of the town hall above – advance to (updated) 59 minutes into the clip. Meantime, we’re covering the HPAC meeting next; as announced earlier today, the West Seattle Transportation Coalition has a bridge-focused meeting tomorrow, too.

THURSDAY: Bridge discussion @ West Seattle Transportation Coalition

The third community discussion in two days about the West Seattle Bridge closure has just been announced. The West Seattle Transportation Coalition will have SDOT and Metro guests during its online meeting, 6:30 pm tomorrow (Thursday, April 23rd):

Nothing can totally replace the capacity of the West Seattle Bridge. What are we going to do when the stay-at-home order is lifted and life begins to return to normal? Our meeting will focus on how we will cope going forward. We are going to need innovative and unorthodox ideas to move people and goods. Please join us tomorrow night when we find out what SDOT and Metro already have in the works and what we can do to help.

The meeting link will be here (meeting ID 822 0028 3371).

WEST SEATTLE BRIDGE CLOSURE: Pier 18 explained; project funding suggested

Two more West Seattle Bridge notes, with hours to go until tonight’s town hall:

(WSB photo, last week)

PIER 18 EXPLAINED: If you haven’t already seen this via SDOT Blog, the project email list, or our mention in the morning comment thread – SDOT has published a detailed explanation of the problem it says needs to get fixed first, the Pier 18 bearing. (18 is the one in our photo above, at left, with a pipe running down it.) Writes SDOT’s Sara Davis, “This isn’t the sole cause of cracking on the bridge, but our bridge experts think it is a major part of the problem.” And: “We’re hoping that releasing the bearings helps stabilize the bridge. If it does, then repairing the bridge may be feasible. If it turns out that releasing the bearings does not slow the cracking of the bridge, it means that the factors contributing to the cracking are much more complicated than just those due to the bearing, and that the bridge structure could be irredeemably compromised.”

FUNDING SUGGESTED: Just getting to the point where the bridge is stabilized via shoring will cost an estimated $33 million, SDOT has said – repair or replacement is an as-yet-unknown addittonal cost. So where will the money come from? West Seattle/South Park City Councilmember Lisa Herbold has suggested one possibility is to divert funding from the Center City Streetcar, a project of which she’s been critical in the past. Today in a post opposing the latest “payroll tax” proposal before the council, Councilmember Alex Pedersen – who chairs the Transportation Committee – made the same suggestion, writing, “To accelerate vital infrastructure projects like the West Seattle Bridge, we can redirect funds away from money-losing projects like the Center City Connector streetcar through downtown.”

TONIGHT: West Seattle Bridge discussions @ town hall, HPAC meeting

Reminder of two events tonight addressing the West Seattle Bridge closure:

DIGITAL TOWN HALL: City Councilmembers Lisa Herbold and Alex Pedersen are hosting this, with an SDOT preentation and community Q&A, 5-6:30 pm. You need to RSVP here; the link will be sent about an hour in advance to everyone who RSVPs. (Update: 2,200+ as of this morning, according to Herbold’s office.) That link also will explain how to ask a question. Go here to RSVP. (4:22 pm update: Livestream will be here.)

HPAC MEETING: 7-8 pm, the community council for Highland Park, Riverview, and South Delridge – neighborhoods now carrying the weight of bridge-detour traffic – will meet online, with an SDOT guest. Unlike the city-organized town hall, there is an attendance limit for this meeting, so they ask that only people from those three communities participate. Details are here.
