If you still have questions about the upcoming closure of the Alaskan Way Viaduct – and the other looming traffic-crunch factors – but haven’t made it to any of the meetings where it’s been discussed – here’s your next chance: Monday (November 26th), Delridge Community Center (4523 Delridge Way SW), 6:30-7:30 pm. This one’s a city presentation; the announcement says, “Please join the Seattle Department of Neighborhoods and the Seattle Department of Transportation for an information session on the upcoming permanent closure of the Alaskan Way Viaduct and the other upcoming challenges to our transportation system as we build a better city.” It’s one of five around the city.

P.S. We covered last night’s briefing at the Junction Neighborhood Organization meeting and our report is in the works.

VIADUCT TO TUNNEL: New traffic-info website and other updates as January 11th Highway 99 closure approaches

(WSB photos. Future Alaskan Way surface signal, in what’s still a construction zone where today’s briefing was held)

12:20 PM: Close to where northbound vehicles will enter the new Highway 99 tunnel starting in a few months, WSDOT, SDOT, and Metro just held another update/briefing event for the media.

Part of it was intended to underscore just how much work has to be done during the ~3 weeks between permanent closure of the Alaskan Way Viaduct and opening of the tunnel – this new WSDOT video explains it:

No major new information about the closure period at today’s briefing, but we were there and noted some key points:

-SDOT has launched a new traffic-info website today at (this is where you can, among other things, sign up for neighborhood-specific alerts, which were previewed at a previous briefing)
-Metro is working on a new batch of brochures with information on bus changes
-Metro also notes that during the closure it will be “more dynamic,” with rerouting “on the fly” if needed
-The Water Taxi “two-boat” schedule information should be available online “soon”

(WSDOT’s tunnel/viaduct project administrator Dave Sowers)

-WSDOT says the tunnel will be toll-free into the summer, with tolling probably not starting until July/August
-You’re now warned that this is really just the start of a 5-year period of transportation turbulence in the city
-West Seattleites are reminded again that the three-week Highway 99 closure, and tunnel opening, will be followed by another two weeks or so of work before the new connection for those exiting NB 99 to downtown is ready to open

Otherwise, the big dates ahead are the same – January 4th for the closure of the SB 99 ramp to SODO, January 11th for the Alaskan Way Viaduct permanent shutdown/Highway 99 closure to get connection work done on both ends of the tunnel (again, the WSDOT video above explains), February 2-3 for the goodbye/hello weekend, tunnel opening TBA after that. We recorded today’s briefing and are processing the video, and will add it along with more toplines when ready.

7:42 PM: Here’s our video of the entire briefing:

Speakers were WSDOT’s Dave Sowers, SDOT’s Heather Marx, and Metro’s Bill Bryant. And another reminder – southbound 99 will be closed between the south end of the Battery Street Tunnel and the West Seattle Bridge this weekend for more prep work, starting around 9 tomorrow night and potentially continuing until very early Monday (as usual, we’ll publish an update if the closure ends early). This is a weather-dependent closure, WSDOT says, but so far the weekend forecast looks mostly dry.

One more reminder – next chance to bring your questions directly to transportation reps will be Monday’s meeting of the Junction Neighborhood Organization, 6:30 pm November 19th at the Senior Center of West Seattle (4217 SW Oregon).

Still have questions about the viaduct-to-tunnel transition?

As noted, it’s less than two months now until the January 11th date announced for permanent closure of the Alaskan Way Viaduct and start of a three-weeks-and-then-some-for-us transition. Three things of note:

1. If you’re on-peninsula tomorrow afternoon, you’re invited to a 1 pm information session in Olympic Hall on the south end of South Seattle College (6000 16th SW; WSB sponsor) – details here.

2. Next Monday night, you’re also welcome at the 6:30 pm Junction Neighborhood Organization meeting at the Senior Center/Sisson Building (4217 SW Oregon), which will include a briefing.

3. We’ll be covering another state/city/county media briefing tomorrow – if you have a transition question that’s so far gone unanswered, let us know (in a comment below, or message us) – we’ll do what we can to get the answer.

COUNTDOWN: Alaskan Way Viaduct closes forever in less than 2 months. Plus, reminder of this weekend’s SB closure

As first noted here back on Friday, southbound Highway 99 will close this coming weekend for more work in advance of the viaduct-to-tunnel transition. WSDOT just sent this reminder:

The State Route 99/Alaskan Way Viaduct through Seattle is scheduled to close this weekend at 9 p.m. Friday, Nov. 16 and reopen by 5 a.m. Monday, Nov. 19. Northbound SR 99 will remain open.

Southbound SR 99 will close between the south end of the Battery Street Tunnel and South Spokane Street to allow crews working for the Washington State Department of Transportation to finish paving work near South Atlantic Street. The work must occur before crews can open the new SR 99 tunnel in early 2019.

The paving work requires good weather and will be rescheduled if heavy rain is expected.

This gives us the opportunity to note that the permanent closure of the Alaskan Way Viaduct is now less than two months away – January 11th, as announced two months ago. WSDOT says it’ll then need about three weeks to “realign 99” before the tunnel can open; the exact opening date isn’t set yet, but WSDOT did announce recently that a pre-opening weekend of viaduct goodbyes and tunnel hellos is set for February 2-3. (By the way, we did verify with the King County Water Taxi that it will NOT be offering weekend service for that event – it’s doubling up during the shutdown, but as with the standard winter service, weekday commuter periods only.)

P.S. If you still have questions about getting around post-viaduct, be at next Monday’s Junction Neighborhood Organization meeting (6:30 pm November 19th, Senior Center/Sisson Building, 4217 SW Oregon) – city/county/state reps are on the agenda to talk about it.

CLOSURE ALERT: SB Highway 99 scheduled to be closed next weekend

November 9, 2018 4:00 pm
|    Comments Off on CLOSURE ALERT: SB Highway 99 scheduled to be closed next weekend
 |   Alaskan Way Viaduct | West Seattle news | West Seattle traffic alerts

Early alert that southbound Highway 99 is scheduled for closure next weekend (late Friday, November 16, through early Monday, November 19th), between the (updated) south end of the Battery Street Tunnel and the West Seattle Bridge. This is described as a closure “for joint and spall repairs.” It’s weather-dependent, so rain will postpone it.

Want to say goodbye to the Alaskan Way Viaduct and hello to the Highway 99 tunnel? ‘Grand opening party’ February 2-3

WSDOT has long said that there’d be a public goodbye/hello party of some sort on the Alaskan Way Viaduct and in the new Highway 99 tunnel before it opens for use. This morning, the details are out. First, the news release:

Early next year, the public will have a unique weekend to run, bike, or simply explore Seattle’s past, present, and future.

Slated for Feb 2 and 3, the Washington State Department of Transportation and city of Seattle will host a grand opening celebration to mark the completion of the new State Route 99 tunnel, the final days of the viaduct, and an improved and reconnected waterfront.

Bookended by a fun run and bike ride, the weekend festivities also include a ribbon cutting, an art festival on the viaduct to celebrate the future waterfront, a public walk through in the new SR 99 tunnel, and interactive science, technology, engineering and math (STEM) activities at the tunnel’s portals. Live music and food trucks will round out the celebration.

“This family-friendly event is a celebration for the Puget Sound region, and a big step forward for Seattle,” said David Sowers, WSDOT deputy administrator of the Alaskan Way Viaduct Replacement Program. “Event activities span from the stadiums to the Space Needle, so for the best experience, we’re encouraging people to plan their weekend and reserve tickets early.”

Saturday event schedule

WSDOT will kick off the weekend early Saturday morning, Feb. 2, with a community fun run sponsored by the HNTB Corporation. The 8K route will take runners through the new tunnel, on to the viaduct, and through the Battery Street Tunnel.

Officials will then cut a ribbon near the south portal, officially opening North America’s largest bored tunnel. At that time, the public can explore:

· The new SR 99 tunnel.

· An arts festival featuring over 100 local artists, installations and a community celebration on the viaduct.

· Community festivals near the stadiums and Seattle Center, with food trucks, live music and STEM activities.

· An interactive “Excavation Station” presented by Dragados U.S.A. that will show how crews used the tunneling machine Bertha to drill and build the 5-story tunnel under Seattle.

Sunday event schedule

On Sunday, Feb. 3, the weekend celebration closes with a bike ride sponsored by Cascade Bicycle Club. The 12-mile route will give cyclists their only opportunity to ride on both the upper and lower decks of the tunnel and viaduct.

Free and paid registration for events

WSDOT encourages participants to visit the Step Forward website to register for the following weekend events:

· Free tickets to explore the tunnel and viaduct on Saturday. Those who register gain entry priority.

· Paid entry to the Saturday morning fun run and/or Sunday morning bike ride. The public must register in advance in order to participate.

It’s complicated so we browsed the site for shortcuts. For one, if you’re interested in the run, the sooner you register, the lower the price – we checked the site and it’s $35 for the first 5,000 participants, going up from there. (The bike ride does not have the same fee structure.) For two, if you’re just interested in a (free) walk onto the Viaduct, that’s Saturday afternoon, but you still need (free) tickets.

P.S. The Alaskan Way Viaduct’s permanent closure is still on for January 11th.

Another pre-opening milestone for the Highway 99 tunnel

(This afternoon’s view from construction-site camera looking south over northbound tunnel entrance)

As the planned Alaskan Way Viaduct closure gets ever closer – we’re now 2 1/2 months from January 11th – WSDOT has announced another tunnel project milestone:

Close followers of the project know that our website is home to an archive of contractor Seattle Tunnel Partners’ monthly schedule updates. These updates don’t show all the construction that’s happening on the project, but they do give an indication of critical work activities that must be completed to achieve an important contract milestone – “substantial completion” of the tunnel.

STP reached substantial completion earlier this month. This is the first of three contract milestones in STP’s work on the tunnel. It means the tunnel is far enough along for STP to officially hand the facility over to WSDOT. It doesn’t mean STP’s work is done, but it does mean the tunnel could be technically operated as designed.

What comes next is a variety of wrap-up work elements that, once completed, will result in the tunnel reaching the second milestone, known as “physical completion.” Meanwhile, as STP works toward physical completion, WSDOT will continue to train maintenance and operations staff to ensure the tunnel and those responsible for its operation are ready to go in early 2019.

The final contract milestone, aptly named “final completion,” will be achieved when paperwork and documentation are done. The tunnel will open before this final milestone is reached. You can see the latest schedule update – along with those from previous months – on our schedule page.

P.S. Got questions about the upcoming viaduct-to-tunnel transition? Your next chance to ask them is this Thursday night, when WSDOT reps are among the guests at the North Highline Unincorporated Area Council meeting in White Center (7 pm Nov. 1st, 1243 SW 112th).

TRAFFIC ALERT: NB Highway 99 reopens

October 20, 2018 3:28 pm
|    Comments Off on TRAFFIC ALERT: NB Highway 99 reopens
 |   Alaskan Way Viaduct | West Seattle news | West Seattle traffic alerts


The final scheduled inspection of the Alaskan Way Viaduct is complete and State Route 99 northbound is now open through Seattle – with the exception of the Royal Brougham Way on-ramp. Construction crews working for the Washington State Department of Transportation expect to open the on-ramp at Royal Brougham Way by 7 p.m. tonight, Oct. 20.

Southbound lanes of the Alaskan way Viaduct/SR 99 remain closed all weekend for construction and will reopen by 5 a.m. Monday, Oct. 22. The southbound highway is closed between the Battery Street Tunnel and South Spokane Street.

FOLLOWUP: Tunnel tolls finalized, plus other Highway 99 notes – including a change to this weekend’s closure plan

(WSDOT photo: NB view inside the tunnel, from August)

1:34 PM: The state Transportation Commission has finalized the toll rates for the Highway 99 tunnel – $1 to $2.25, depending on daypart, providing you use Good To Go. From the announcement:

On weekdays, tolls will be $1.50 during the morning peak commute (7 a.m. to 9 a.m.), $2.25 during the evening peak commute (3 p.m. to 6 p.m.), and $1.25 during non-peak hours between 6 a.m. and 11 p.m. Overnight (11 p.m. to 6 a.m.) and weekend tolls will be $1.00. Toll rates will increase by 3 percent every three years beginning in July 2022, subject to annual review by the Transportation Commission.

The Transportation Commission has previously determined that there will be consistent exemptions on all toll facilities for public transit, emergency responders, highway maintenance vehicles, school buses and qualified private buses, which serve the public or commuters.

State law requires that SR 99 tunnel tolls be used to repay $200 million borrowed to build the tunnel as well as related debt service costs, and ongoing operations, maintenance, and safety costs.

Drivers will not be charged immediately when the tunnel opens in early February. The start date has not been set, but it will apparently be months after the tunnel opens rather than weeks – this WSDOT Blog report about traffic-pattern changes expected when the tunnel opens says tolling is “expected to begin as soon as summer 2019.” In the meantime, until tolling begins, the report says, WSDOT is projecting more drivers will use the tunnel than currently use the Viaduct. … While we’re discussing Highway 99, yet another reminder that it will be closed BOTH WAYS this weekend, starting Friday night (October 19th) for inspection plus some viaduct-to-tunnel-transition work. As always, if the closure ends early, we’ll update you here.

4:21 PM: And we have an update already. The NB part of this weekend’s closure will be shorter. From the WSDOT website: “Northbound SR 99 will close Saturday, Oct. 20 at 6 a.m. and reopen Saturday afternoon by 5 p.m. The southbound closure remains unchanged.”

TRAFFIC: SB 99 closure continues; next weekend, 99 will close in both directions

So far, this weekend’s Highway 99 closure (SB between the Battery Street Tunnel and West Seattle Bridge) has NOT ended early. But we want to take a moment to remind you about NEXT weekend’s both-ways closure – including the last-ever scheduled inspection of the Alaskan Way Viaduct – planned to start late Friday, October 19th, continuing to early Monday, October 22nd.

Viaduct-to-tunnel transition: Toll decision expected next week

(WSDOT photo)

The Highway 99 tunnel is set to open in early February, after three weeks of road-realignment work following the Alaskan Way Viaduct‘s permanent closure on January 11th. It’ll be toll-free for a trial period at the start. Once that’s over – what will you be charged? That decision is expected to be made by the State Transportation Commission next week, after one last public hearing (11 am Tuesday, October 16th, in Olympia). Here’s the plan, with rates ranging from $1 to $2.25 (provided you sign up for Good To Go):

If you can’t be at that hearing but have something to say, the commission is taking written comment through tomorrow – scroll down this page to find out how.

P.S. Reminder that more prep work brings a closure oF SB 99 this weekend – details here.

State, city, county team up for Highway 99 briefing @ West Seattle Transportation Coalition

By Tracy Record
West Seattle Blog editor

A week and a half after the big news that the Alaskan Way Viaduct will close forever on January 11th, with three weeks of Highway 99-less-ness to follow before the new tunnel opens (and other traffic effects beyond that), the West Seattle Transportation Coalition got a high-level briefing.

Leading that briefing last night: WSDOT’s Viaduct/99 project boss Brian Nielsen, SDOT’s downtown-mobility director Heather Marx, and King County’s Chris Arkills.

There were a few new bits of information – but even the not-so-new info bears hearing over and over as the 99-less period approaches.

Marx began with the overview that getting around the city is about to change – “it’s not going to be super-fun, for a few years” – with the promise that after those “few years,” things will be much better.

She showed the five pillars of how “downtown mobility” will be managed.

She made way for Nielsen, who promised specifics on “what’s going on in the Viaduct program now and the next couple years.” The number 5 figured into his early going, too – 5 things that have to be completed before the tunnel can open.

1st weekday since Metro’s service change, with reminder for riders on Viaduct-using routes

This is the first weekday since Metro‘s latest “service change” kicked in on Saturday. For West Seattle, Routes 56, 57, 120, and RapidRide C Line have added weekday trips. But there’s one more important note: As noted here last Tuesday, timetables were printed with the belief that the Viaduct-to-tunnel Highway 99 change was happening soon – but as you no doubt have heard by now, it’s not happening until January 11th. So Metro wants to be sure you know this:

Transit service will continue to operate on the Alaskan Way Viaduct until early 2019

In a revision to previously published information for Metro’s September 22 service change, routes 21 Express, 37, 55, 56, 57, 113, 120, 121, 122, 123, 125 and the RapidRide C Line will continue to operate on the Alaskan Way Viaduct, and along Seneca and Columbia streets, until early 2019, instead of changing to SODO surface streets as previously planned.

The Alaskan Way Viaduct is now scheduled for closure in early 2019, and until it is closed, the routes that have been operating on it will continue to do so.

Updated schedules are online
While Metro works to update all of its data information systems, use the timetables posted on Metro’s website to plan your trip. During morning peak hours, some buses may arrive in downtown Seattle slightly earlier than scheduled.

When using Metro’s online Trip Planner, watch for the ‘Alert!’ symbol on affected itineraries, and check posted service advisories for routing or stop revisions. Revisions will be fully integrated in the Trip Planner by or before October 20.

New red timetables
Routing and operating times in new red paper timetables for viaduct routes that were distributed prior to September 22 do not reflect this late change to actual operation.

Affected timetables are being revised. Use online timetables or note that, because scheduled running time was added for the expected surface street operation, buses may seem to run earlier or later than the times shown in those timetables.

Downtown routing revisions for some viaduct routes
In the downtown area, some morning peak hour buses have revised routing. After exiting the viaduct, routes 21 Express, 121, 122, 123 and 125 that used to operate a short distance north on 1st Avenue or south on 2nd Avenue are all now operating via Seneca Street to 3rd Avenue, where they will continue north on 3rd, except for Route 125, which will continue south on 3rd.

To get to points south of Seneca St, transfer to applicable service southbound on 2nd or 3rd avenues from posted bus stops just south of Seneca St, or enter the transit tunnel at 3rd Av and Seneca St and transfer to southbound buses or Link light rail.

Onboard announcements
Some onboard stop or landmark information for viaduct buses in the downtown Seattle area may temporarily not be announced or may be announced incorrectly.

Listen for operator announcements or check with your driver if you need assistance with stop information for your route. These systems are also in the process of being updated.

Service change information
Information about all fall service revisions is posted online, and is included in new red timetables.

P.S. If you have questions about January’s Viaduct-to-tunnel transition, bring them to the West Seattle Transportation Coalition meeting this Thursday (September 27), 6:30 pm at Neighborhood House High Point (6400 Sylvan Way).

TRAFFIC ALERT UPDATE: Highway 99 now fully reopened

Again this weekend, the Highway 99 closure has ended earlier than scheduled. As you can see in the “live” traffic camera above, NB 99 is now fully reopened after completion of another round of work relate to the Viaduct-to-tunnel transition.

TRAFFIC ALERT UPDATE: NB Highway 99 reopens from stadium zone northward

As promised, WSDOT has reopened *part* of northbound Highway 99. It’s now open from the stadium zone northward, which will be extra-busy tomorrow because of the Seahawks game. But NB 99 remains closed between there and the West Seattle Bridge, so if you’re outbound headed off-peninsula, you’re going to have to use an alternate route. That section is scheduled to remain closed until early Monday but as usual, we’ll be checking, and will publish an update if it reopens earlier than scheduled. P.S. WSDOT explains here what this closure is about.

VIADUCT NOTES: Another Highway 99 closure this weekend; plus, bus routes’ future

Two Alaskan Way Viaduct/Highway 99-related notes on this day after The Big Announcement (WSB coverage here) that the AWV’s permanent shutdown for the tunnel transition (and then demolition) won’t happen until January 11th:

ANOTHER CLOSURE THIS WEEKEND: WSDOT confirms that another Highway 99 closure north of the West Seattle Bridge is planned this weekend, this time northbound, according to spokesperson Laura Newborn. When we checked with her this morning, she was awaiting confirmation on the Friday night (September 21) start time (update: 9 pm), but added that “WSDOT plans to open up the NB ramp at Royal Brougham so NB SR 99 will be accessible after the Seahawks game on Sunday.” That’s assuming the closure doesn’t end early, as last week’s southbound closure did.

BUS ROUTING AFTER THE PERMANENT CLOSURE: Looking ahead to its next “service change” this Saturday, Metro created timetables with information about what happens to the 12 routes that use the Alaskan Way Viaduct, once it closes. Below are the links to PDFs of each timetable and the language each respectively contains regarding rerouting during the Highway 99 closure:

C Line

(During the Highway 99 closure) … the C Line will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. The C Line will continue to operate via 3rd Ave midtown.

Route 21

(During the Highway 99 closure) … Route 21 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. All Express service will operate exclusively via 3rd Ave midtown; Local service will remain unchanged midtown

Route 37

(During the Highway 99 closure) … Route 37 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. All Route 37 service will operate via 3rd Ave north of Columbia St during this time.

Route 55

(During the Highway 99 closure) … Route 55 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. Route 55 will operate via 3rd Ave, but otherwise remain unchanged midtown.

Routes 56 and 57

(During the Highway 99 closure) … routes 56 and 57 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. Both routes will operate via 3rd Ave, but otherwise remain unchanged midtown.

Route 113

(During the Highway 99 closure) … Route 113 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. Midtown, Route 113 will shift operation from 1st Ave and 2nd Ave to 3rd Ave.

Route 120

(During the Highway 99 closure) … Route 120 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. Route 120 will operate via 3rd Ave, but otherwise remain unchanged midtown.

Routes 121, 122, 123

(During the Highway 99 closure) … routes 121, 122 and 123 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. Midtown, the three routes will shift operation from 1st Ave and 2nd Ave to 3rd Ave

(added) Route 125

(During the Highway 99 closure) … Route 125 will be rerouted through SODO via 4th Ave S, and via 2nd Ave and 3rd Ave south of Columbia St. Midtown, Route 125 will operate exclusively via 3rd Ave.

Since the timetables have language suggesting that the permanent AWV closure was expected to start around the end of this month, some might be confused, so we contacted Jeff Switzer of Metro, who reiterates, “The printed timetables for the 12 routes that use the viaduct will be accurate at the time the tunnel opens. The interim pathways defined during the closure are set, however, additional bus stops are under consideration. Buses will continue to use the viaduct and their current paths, and riders can expect the same trip duration, until the viaduct closes.” The mention of “additional” stops dovetails with what Metro deputy general manager Terry White said at yesterday’s media briefing, that stops are still being finalized.

VIDEO: Highway 99 closure for viaduct-to-tunnel transition set to start January 11

(Added 6:20 pm: Full unedited video of briefing)

12:55 PM: We’re at a WSDOT media briefing at Colman Dock, where WSDOT has just announced the Highway 99 closure for the tunnel transition won’t start until January 11. More to come.

1:02 PM: Here’s the full news release:

Mark your calendars. In early 2019, the new State Route 99 tunnel will open, offering travelers a direct route from Seattle’s stadiums to the Space Needle.

To open the tunnel, the Washington State Department of Transportation must first realign the state highway, and then move SR 99 from the seismically vulnerable Alaskan Way Viaduct into the tunnel. This intensive work will last about three weeks and prompt the longest major highway closure to ever hit the Puget Sound region.

“The opening of the SR 99 tunnel will be an historic event in the state’s transportation history,” said Brian Nielsen, administrator of the Alaskan Way Viaduct Replacement Program. “Before we can celebrate, we have to get through an unprecedented closure that will require all of us to change our behavior.”

WSDOT’s current plan is to close SR 99 through Seattle beginning Friday, Jan. 11, 2019. Closing SR 99 through Seattle is the only way crews can finish building the highway and the eight new ramps that will allow travelers to enter and exit the new tunnel

Travelers should expect region-wide congestion for up to six weeks as crews complete final connections to and from the new tunnel. In addition to the three-week closure:

*The off-ramp from southbound SR 99 to South Atlantic Street will permanently close one week earlier than the viaduct.

*The new off-ramp from northbound SR 99 to South Dearborn Street will require up to two weeks of additional work after the tunnel opens.

Get ready, make a plan

When the viaduct closes, 90,000 drivers who normally use the Alaskan Way Viaduct will need to find another way to get to, or through, downtown Seattle. During past Alaskan Way Viaduct closures, congestion increased on all major highways throughout Puget Sound as well as on local streets.

While WSDOT is working closely with the Seattle Department of Transportation, King County Metro and other key transportation agencies to keep traffic moving during this challenging time, help from drivers is critical.

“We need drivers to change their habits for three weeks to prevent gridlock,” said Nielsen. “We recognize everyone’s strategies will be different based on their needs, but consider other ways to get to and from your destination, if you can.”

Closure timing

When Seattle Tunnel Partners finished disassembling the tunneling machine Bertha in 2017, WSDOT estimated the tunnel would be open in early 2019. While there was optimism this date could be moved up, a number of factors influenced the decision to stay with the early 2019 date:

Construction progress: WSDOT has several contractors that must complete work to be ready for the three-week SR 99 closure. Scarsella Brothers, Inc. will then build the final tunnel and ramp connections. Some of this work, like road striping, is weather dependent.

Public notice: Starting in January ensures that contractor work will be complete and we can provide a specific date much further in advance. The public’s help will be critical and this will give everyone time to plan.

Holiday travel and commerce: WSDOT and its partner agencies are committed to keeping people and goods moving during the busy holiday season. Avoiding a major highway closure between Thanksgiving and New Year’s Day helps achieve this goal. There are also fewer major events in early 2019 than there are during the last quarter of 2018.

Per the Legislature’s decision, the SR 99 tunnel will be tolled as a part of the project’s financing plan. The tunnel will be free to use when it first opens.

Additional details about the closure, tunnel opening and the future tolling of the tunnel can be found at

(WSB photo: Briefing in ferry holding zone downtown)

1:50 PM: The briefing is over and we’re headed back to HQ. We recorded it all on video and will be uploading that. Also, some West Seattle-specific details: Paul Brodeur from the King County Water Taxi said it will run a two-boat schedule on weekdays during the closure, with shuttles also doubled, and there will be extra parking including a lot at Pier 2, at Don Armeni, and along Harbor Avenue.

3:26 PM: Bus reroutes during the closure are already mentioned in route-specific pamphlets as part of Metro’s service-change announcement – but the language suggests they were expecting the closure to be much sooner, so we’re asking Metro if the January timing will change anything. Metro’s new deputy general manager Terry White said at the briefing that the stops for the 12 routes that will have to be rerouted are still being finalized.

6:20 PM: Just added our full unedited video of the briefing and Q&A from this afternoon.

EARLY REOPENING: SB Highway 99 closure is over

Though southbound Highway 99 was scheduled to be closed until late tonight, the closure has ended early. It’s now open again (as the “live” traffic-camera image above verifies)!

CLOSURE: New hours for southbound Highway 99 shutdown this weekend

The SB Highway 99 closure for this weekend, first noted here last weekend has new hours. From WSDOT:

The contractor working for the Washington State Department of Transportation has shortened the amount of time needed for paving work this coming weekend, so the closure of southbound State Route 99 through Seattle will start a little later and end a little earlier. The southbound viaduct will close at 11:59 (pm) Friday, Sept. 14 and run through 11:59 (pm) Sunday, Sept. 16.

Southbound SR 99 will be closed between the south end of the Battery Street Tunnel and South Spokane Street so crews can pour concrete near Atlantic Street. This will help advance some of the work needed to open the new SR 99 tunnel.

Looking ahead: Before the new SR 99 tunnel can open, WSDOT will have to close the viaduct for approximately three weeks. The lengthy closure is unavoidable as it is the only way crews can #realign99 into the tunnel and complete eight new entrance and exit ramps.

WSDOT does not yet have a date for the start of the three-week closure, but will give a minimum of one month’s advance notice to help travelers plan ahead as much as possible.

Back to this weekend – WSDOT has just postponed plans for lane/ramp closures on NB I-5. But the 99 work is still on as of right now.

No SB Highway 99 closure THIS weekend – but one IS planned a week later

The decision’s in. No Highway 99 closure this weekend, but WSDOT says one IS on the horizon. The announcement:

This weekend’s scheduled closure of southbound SR 99 through Seattle has been canceled. The viaduct will be open all weekend.

There is another full southbound closure scheduled for the following weekend. The road will be closed from 9 p.m. Friday, Sept. 14 through 5 a.m. Monday, Sept. 17 between the south end of the Battery Street Tunnel and South Spokane Street.

Contractor crews working for the Washington State Department of Transportation will be completing pavement work needed for the Alaskan Way Viaduct Replacement Program. Drivers are encouraged to plan their trip before they go, and expect delays.

Highway 99 closure this weekend? Maybe

If you read SDOT’s “What’s Moving Seattle” roundup of events and road work, you might have noticed a SB Highway 99 closure mentioned for this weekend. That’s not listed on the WSDOT websites anywhere, so we checked with 99 spokesperson Laura Newborn. She says the final call on whether the closure is on or off will be made tomorrow.

WEEKEND TRAFFIC ALERT UPDATE: New information on NB 99 closure

Thanks to Jennifer for catching that the weekend northbound Highway 99 closure we mentioned yesterday had changed from Friday/Saturday/Sunday nights to “all weekend long.” But there’s now another change beyond the one she had spotted on the WSDOT site. While we were corresponding with spokesperson Laura Newborn about the change, she got word minutes ago that the NB 99closure will *only* extend from the West Seattle Bridge to Atlantic Street. That means the elevated Alaskan Way Viaduct itself, from the stadium zone northward, WILL remain open all weekend.

To recap:

*NB Highway 99 closed Friday night to early Monday, between West Seattle Bridge and Atlantic St.
*No change in NB I-5 closure – Offramp to West Seattle Bridge and Columbian Way will be closed 9 pm Friday-5 am Monday

Another peek inside the opening-before-too-long Highway 99 tunnel

No date set yet for the three-week Highway 99 closure that will precede the tunnel’s opening, but WSDOT is providing another peek inside the almost-ready tunnel today, along with this explanation:

… Crews are using stencils to paint “running man” symbols on walls in both directions of the tunnel.

The green icons are spaced about 50 feet apart on the west walls of the southbound (upper) and northbound (lower) roadways. As shown in the photo, arrows point the way to the nearest exits, along with the distances to them.

If the seven-foot-tall green stick figures don’t get your attention, flashing lights at each of the tunnel’s emergency exits and electronic signs will provide additional guidance.

Crews are also striping the roadway inside the tunnel, according to today’s update from WSDOT, which continues to promise that it will provide at least one month’s notice before the three-week closure, which will be followed by two more weeks of work on the ramp that West Seattleites will use to get into downtown south of the tunnel entrance.
