One more reminder – Harbor and Alki Avenues will be closed from Don Armeni to 63rd SW all Sunday morning because of the West Seattle 5K (co-sponsored by WSB), and then afterward, starting around 11 am, traffic will remain restricted to residents from Don Armeni to the start of the actual Seattle Summer Streets closure at 56th. That lasts until 5 pm. And the city now has an extensive list of what activities you’ll find tomorrow and where – see it here (PDF). There’s also an Alki bus detour map – see that here (PDF). And even if you’re not signed up for the West Seattle 5K, just show up at the Alki Bathhouse starting at 8 am for last-minute registration.

The West Seattle Bridge-to-Battery Street Tunnel section of Highway 99/Alaskan Way Viaduct is closed all weekend for continuing reinforcement work, pre-tunnel construction – and that can lead to scenes like this one, shared by Anne from Ventana Construction (WSB sponsor). You can check West Seattle-relevant traffic cams “live” on the WSB Traffic page if you have to head that way before the scheduled reopening early Monday.

PRESIDENTIAL VISIT: President Obama will be in Seattle (flying into and out of Boeing Field) for much of the day on Thursday, including a downtown stop, and that means increased security, as announced by Metro (note a downtown road closure is mentioned too) **note, this is the text of a revised announcement received AFTER the original one we published**:

Thursday’s presidential visit will affect bus service

Convention Place Station in downtown transit tunnel will be closed to pedestrians

President Barack Obama will visit Seattle on Thursday, May 10, and increased security in the downtown area will affect bus service for both King County Metro Transit and Sound Transit.

From about 9 a.m. to 4 p.m., Convention Place Station (CPS) in the Downtown Seattle Transit Tunnel will be closed to all pedestrian access. Buses will continue to travel through CPS, but will not stop there. No passengers will be allowed to board or exit buses in the station, or access the tunnel from the CPS entrance at 9th Avenue and Pine Street.

During this time please board or exit all tunnel buses at the other four tunnel stations, or at their regularly posted surface street stops before they enter or after they leave CPS. Sound Transit Link light rail service is expected to operate normally in the tunnel during this time.

Additionally, from about 9 a.m. to about 4 p.m. on Thursday, Pine Street will be closed west of I-5. During this closure there will be no bus service on Pine Street between I-5 and 3rd Avenue.

Because of street closures and traffic congestion, bus passengers should expect delays throughout the day on Thursday. This could affect bus service in other parts of the county as well. Please allow extra travel time on Thursday and to be prepared for traffic conditions to change..

BEACH DRIVE ROAD REPAIRS: We reported on Tuesday that SDOT is fixing the rutted road surface south of the disputed slide zone, which is NOT part of the project, as it remains the subject of lawsuits and is going to mediation. Today, SDOT sent a news release with more details on the repair work set for next week:

A portion of Beach Drive SW will get much-needed repairs next week, weather permitting. SDOT crews will resurface a segment about 800 feet long in the blocks with addresses from 6200 to 6600.

Tomorrow, May 10, a contractor will prune overhanging trees in this area to provide adequate space for equipment to operate and to meet the city’s clearance requirement.

The paving crews plan to work from May 15 to May 18, from 7 a.m. to 7 p.m. They will grind off the old surface and lay new asphalt from curb to curb.

One lane will remain open for each direction of traffic and a Police Officer will assist drivers through the area.

This work is a part of SDOT’s annual paving program and is funded by the Bridging the Gap transportation initiative approved by Seattle voters.

ORIGINAL 7:07 AM REPORT: It’s on the 911 log and WSDOT confirms it via Twitter – “part of the N/B I-5 on-ramp from the W. Seattle (Bridge) is partially blocked due to a collision.” We’ll monitor that (and any other traffic challenges ahead) with updates as we get them.

7:30 AM UPDATE: Added the “live” image from the WSDOT camera pointed that way. The truck’s still there but the fire/medic crews have cleared out.

7:39 AM UPDATE: WSDOT says the scene is now completely clear. However, residual backups take a while to clear, especially in peak traffic, so your commute might still take extra time at this point.

- May 7-10, the westbound lanes of the Spokane Street Viaduct will be closed nightly at SR 99. All westbound traffic will exit at Harbor Island and be detoured via the lower Spokane St roadway/low bridge to West Seattle. The southbound SR 99 ramp to West Seattle will remain open. [This starts at 9 pm each night.]

- Beginning May 9 at 7 PM, expect changes on the Alaskan Way waterfront overnight. Traffic will be moved off of Alaskan Way and will be relocated underneath the Alaskan Way Viaduct between S King St and Madison St. On the night of May 9th, S Washington St, Yesler Way, Columbia St and Madison St will be closed. Officers will be on-hand Thursday morning to assist traffic with the new road network and traffic patterns.

- May 18-21, the Alaskan Way Viaduct (SR 99) will be closed between Denny Way and S Spokane St in both directions Friday night through Monday morning. All on- and off-ramps will also be closed.

The May 9 mention is the one that goes with the ferry-terminal-reroute video we’ve been featuring here – the big change will kick in the morning of May 10th. Other areas of the city have various smaller closures too, and you can see the complete grid for what’s in the works by going here.

As promised, we’ll be publishing updates on whether May Day marching/rallying is affecting the commute through downtown, and this way. (Right now, a bout of wild weather has hit – with a hail-infused deluge hitting West Seattle about 10 minutes ago and headed east – though it looks like the sun will return once it moves through). Stay tuned for toplines.

ONGOING COVERAGE: Our partners at the Seattle Times have been publishing quick, short updates here. … The Seattle Police SPD Blotter has published a roundup of vandalism damage and arrests (2 as of 3 pm) ad promises updates … (added 4:21 pm) KING 5 also has ongoing online coverage incorporating tweets, photos and other quick updates from their staff and other local media. … To check on Metro delays, you can watch their commute-updates website (we’re checking it too).

4:28 PM UPDATE: KING reports via Twitter that a group of marchers is at 1st and Bell. This would be separate from the prescheduled march that was to gather south of downtown half an hour from now. One other note: The Times mentioned school-bus delays; we checked with Seattle Public Schools and that’s ONLY the buses running in downtown/Capitol Hill – no effects here.

4:37 PM UPDATE: Only “minor” delays downtown for transit, Metro reports.

UNRELATED TRAFFIC UPDATE AT 4:57 PM: Just got a tip from Lisa that there is a car vs. semi crash at the west end of the “low bridge,” no injuries reported so far. We’re en route to check.

(Photo by WSB’s Patrick Sand – car is up against right side of the semi, right side of photo)
5:22 PM UPDATE: That incident is causing some trouble coming off the low bridge, but traffic’s being routed around it. Adding a photo in a moment. Meantime, we just got a text from someone saying southbound 99 is actually LIGHTER headed this way than usual. (Here’s a new SDOT camera we will be adding to the WSB Traffic page – looking north at the southbound Viaduct flow at King St.)

And from downtown, we are adding photos taken by WSB contributor Christopher Boffoli, who says the biggest effect he noticed while downtown was the increased police presence.

5:46 PM UPDATE: Police now report eight arrests so far since this morning. The city, meantime, says it’s activated its Emergency Operations Center to help with public-safety concerns. The prescheduled march is heading eastbound on Pike from 4th as of right now.

6:25 PM UPDATE: The rally downtown is under way. We’ve been monitoring the scanner and the ongoing coverage from citywide media. Metro says marchers are northbound on 4th and that some buses are stuck in a jam downtown.

Drove up Admiral Way hill north of the bridge a little while ago to confirm that the repaving work has begun – it has. (Here are the details from SDOT; it’s scheduled to continue through Friday.

Meanwhile, turns out SDOT didn’t inspect the Fauntleroy Expressway section of the bridge as expected yesterday – so the work is rescheduled for the next two days:

The Seattle Department of Transportation previously announced that they would be inspecting the Fauntleroy Expressway bridge deck (the raised roadway at the west end of the West Seattle Bridge) on April 30th. Due to unexpected mechanical issues, the work has now been rescheduled for Wednesday and Thursday, May 2nd & 3rd between 8 am and 3 pm.

The inspection team will establish short-term lane closures of the right-hand lane, beginning on the westbound side, using truck-mounted traffic warning devices. The inspection team will make short-term (15 minutes) stops at any given location along the bridge deck. After completing the westbound route the team will then inspect eastbound, toward Downtown Seattle, also along the right-hand lane. The entire inspection will be completed by 3 p.m. on the given day. (When working during the morning commute period, activities will take place in the lanes of travel that are in the opposite direction of peak traffic flows.)

These closures are required as part of the seismic retrofit of the Fauntleroy Expressway, to make it more likely to withstand the force of a major earthquake. The work is funded by the “Bridging the Gap” transportation levy approved by Seattle voters in November 2006.

Transit service – and all traffic – in downtown Seattle will likely be delayed during the Tuesday afternoon commute and into the evening due to a May Day march and other activities. Bus riders should be prepared for transit service delays – and possible reroutes. This could affect bus service both on surface streets and possibly the transit tunnel.

One march is planned to leave the Central District at 5 p.m. and travel along South Jackson Street to Fourth Avenue to the Wells Fargo Building on Third Avenue between Madison and Marion streets. There could be additional May Day activities in other locations that could also delay or disrupt traffic and transit.

If possible, people may want to leave work early Tuesday. They should also give themselves extra time to travel through the downtown area. Metro may have to temporarily reroute buses if streets are closed or become blocked.

Metro will be using its Eye on the Metro Commute blog and Twitter account to do its best to keep customers informed about the transit disruptions on Tuesday afternoon and evening.

(SDOT also has an alert, mentioning that 2nd might have to be closed.) We of course will keep you updated here (and via the WSB Facebook page) too. Nothing major is planned in West Seattle tomorrow so far as we have heard.

1:37 PM: More Monday road woes – just got a text about a crash at 8th and Roxbury, and the 911 log shows a 2-unit dispatch. (added) It’s on the westbound side, and Seattle Police have called for extra reinforcement to manage traffic, so avoid the area if you can. We’re en route for a look.

1:52 PM UPDATE: Per the scanner, the crash is actually a hit-and-run, and they’re looking for a driver described as female, in her 30s, 5-foot-5, blue shirt, blue pants. Our crew just arrived and is trying to find out more about that, but also reports that westbound traffic is being diverted onto 7th SW. At least one person is hurt; an ambulance is on scene.

2:13 PM UPDATE: Added a photo. Police tell us that the car in the foreground, with the least damage, is the one whose driver left the scene; the one behind it, with more damage, is the one whose driver was taken to the hospital.

TRAFFIC NOTE #1: As announced last week, today’s the day SDOT plans to inspect the west end of the West Seattle Bridge – the Fauntleroy Expressway section, which has been getting an earthquake-safety retrofit since last year – which means “rolling slowdowns” between 8 am and 3 pm. Here again is how they explain it:

The inspection team will establish short-term lane closures of the right-hand lane using truck-mounted traffic warning devices. The inspection will begin near West Seattle and move westbound. The inspection team will make short-term (15 minutes) stops at any given location along the bridge deck. After completing the westbound route the team will then inspect eastbound, toward Downtown Seattle, also along the right hand lane. The entire inspection will be completed by 3:00 p.m.

TRAFFIC NOTE #2, ADDED AT 7:26 AM: Not sure how long this will last, but we just caught word of a truck crash on northbound I-5 at the Ship Canal Bridge that is causing problems through downtown – so if you usually take I-5, be forewarned, it’s slower going right now, and traffic reporters are advising 99 as an alternative, so that may be busier than usual.

8:06 AM UPDATE: WSDOT says the I-5 crash scene is clear now, but the backup will take a while longer to clear since it’s heavy-traffic commute time.

The Seattle Department of Transportation will be inspecting the Fauntleroy Expressway bridge deck on April 30th between 8:00 a.m. and 3:00 p.m. The inspection team will establish short-term lane closures of the right hand lane using truck-mounted traffic warning devices. The inspection will begin near West Seattle and move westbound. The inspection team will make short-term (15 minutes) stops at any given location along the bridge deck. After completing the westbound route the team will then inspect eastbound, toward Downtown Seattle, also along the right hand lane. The entire inspection will be completed by 3:00 p.m.

This is part of the Fauntleroy Expressway Seismic Retrofit Project; we took an up-close look at some of the earlier work for this story back in January.

Next week, weather permitting, from Tuesday, May 1, through Friday, May 4, a Seattle Department of Transportation (SDOT) paving crew will be working on SW Admiral Way between SW City View Street and SW Hanford Street. The crew will be grinding down the street surface, making repairs to the base and then paving SW Admiral Way in the northwest direction – uphill – from the eastside curb to the center line. During the work, which will take place between 9 a.m. and 6 p.m. each day, traffic will be in will be reduced to one lane in each direction until 2:30 p.m., then opened up to two lanes northwest bound (uphill) and one lane southeast bound (downhill).

A lane will be provided for bicyclists. Parking will not be allowed in the work zone. Crosswalks and sidewalks will remain open. The project is part of SDOT’s 2012 Arterial Major Maintenance program.

Here’s a map.

Thanks to Bill and Wendy for word of a crash at 35th/Morgan. Bill says no injuries are reported; Wendy says one car is involved that went “straight into the corner, took out the street tree, and hit two U-Haul vehicles. … Antifreeze or something is hissing from the engine compartment because of the tree damage. Front bumper is on sidewalk behind vehicle now.” Both have shared photos.

(Photo by Bill Bacon)
3:19 PM: Two photos added. No SFD medic unit sent to the scene, which would be confirmation that if there were any injuries, they weren’t major.

3:31 PM UPDATE: Just drove through 35th/Morgan – no traffic impediments on 35th; the westbound lane on Morgan by U-Haul (northwest side of the intersection) should clear soon, since the tow trucks is already there to take away the car that hit the U-Haul vehicles.

Sorry we missed the chance to bring you real-time updates during what by multiple accounts was a bad hour or so on the eastbound West Seattle Bridge this morning. We are trying to reach SDOT to see what they can tell us, but a couple of WSB’ers have mentioned road work – possibly painting crews – which were not mentioned in any advance traffic advisories, so far as we can tell; there were no scheduled closures for the weekend, nothing till another round of overnight-only southbound 99/Viaduct closures during the weeknights next week. Though everything seems to be OK now – at least according to the cameras on the WSB Traffic page – let us know if you encounter otherwise. (And if/when you can, please text or voice-call about something like this – even if we’re offline for a bit, which we were because of a panel discussion before the Gathering of Neighbors today, the text/voice calls break through IMMEDIATELY, whatever we’re doing, 24/7 – 206-293-6302 – consider putting it in your phone “contacts” list; traffic is “breaking news” too! Thanks!)

12:26 PM UPDATE: Rick Sheridan from SDOT says it wasn’t their fault:

We’re sorry to hear drivers were delayed. While we are restriping the high-rise bridge today, the earlier collision was the cause of the traffic problem. According to staff on site at the time, traffic was backed up prior to beginning our work and delayed us as well.

Once emergency response dealt with the incident, traffic problems dissipated. The SDOT live cameras show traffic is flowing smoothly now.

The only crash on the 911 log was at 6:53 am (though it doesn’t show non-injury crashes or stalls).
