What’s Moving Seattle | Weekender

Like we said earlier this week, this weekend is hot! But wait, there’s more….there’s preparing for Monday! What’s happening Monday, you ask?


How you get around downtown is changing.

On Monday, we’re optimizing bus service on 3rd Ave by extending bus-only hours. In other words, 3rd Ave will be dedicated for buses and bicyclists from 6 AM to 7 PM, seven days a week.

As the Washington State Department of Transportation plans for a full three-week closure as early as this fall, of SR 99 downtown – the Alaskan Way Viaduct – and the opening of a new SR 99 tunnel under downtown, we’re ramping up our strategy to deal with the traffic impacts in and around downtown.

Today, 3rd Ave is reserved for buses and people biking during the busiest weekday commute times (6-9 AM & 3-6:30 PM, M-F); starting Monday, 3rd Ave from Stewart St to just south of Yesler Way will be reserved for buses and bicyclists, 6 AM – 7 PM, seven days a week. So what does this mean for you? Get the details in our latest SDOT blog.

So have fun this weekend while also remembering this Monday change! The Seattle Police Department will cite people violating new restrictions in the coming weeks, but in the beginning, you’ll see officers educating people driving.


More AWV-related work.

Remember those construction ahead points we noted Aug. 3? Here’s an update…


Utility vault installation:

Through August 21, one WB lane on Madison St will be open, with all other lanes closed between Western Ave and Alaskan Way. The Office of the Waterfront is finishing installation of a vault to maintain utility service to area businesses, once the Alaskan Way Viaduct is demolished.


Installing new traffic signals/markings:

WSDOT expects construction for the Alaskan Way Traffic Switch to wrap up on or around Sept. 27, 2018. Crews are working north from the former ferry queuing lanes near Marion St, into current waterfront parking up to Pike St. They’re installing new traffic signals and marking new traffic lanes to prepare Alaskan Way for 2-way traffic (to be moved out from underneath the viaduct).



Pier 62/63 will impose lane restrictions on Alaskan Way through 8/31/2018 during non-peak travel times.

Columbia 2-way project is substantially complete and final inspections are underway. This project repaved Columbia St before it is converted to 2-way between 1st Ave and 3rd for bus routes, coming from West Seattle after the Alaskan Way Viaduct is demolished.


Rainier Tower construction impacts.

Crane installation:

On August 18, 5th Ave will be closed between Union and University streets to install the project’s third tower crane. Use 2nd and 3rd avenues for SB travel.


Pouring concrete:

September 7 at 10 PM through September 8 (possibly until Sept. 9) there will be full closures of 4th Ave, Union St, 5th Ave, and University St around the project to pour 11,000 cubic yards of concrete – over 1,000 trucks will deliver to the site that weekend.


Other impacts include the continued daily closure of one lane on Union St, 6 AM – 5 PM;  transit lane closure on 4th Ave, 6 AM – 3 PM daily; and sidewalk closures 24/7 on all frontages (Note: Rainier Square building is accessible).
