  • Out of the shadows: double-deck viaduct demolition complete on Seattle’s waterfront

    It has been more than six decades since Seattle’s downtown waterfront enjoyed a full day without the shadow of the Alaskan Way Viaduct.  The last weekend of summer marked the end of the double-deck structure’s reign along the waterfront between Pike Street and South Dearborn Street, near the stadiums.

    This new video captures the tremendous difficulty of the work and the depth of the transformation along Seattle’s waterfront.

    There is still work ahead. Some streets and crosswalks remain closed as cleanup work continues, along with demolition of the viaduct’s ramps north of Pike Place Market.

  • Wall Street closed and Denny Way reduced this weekend for paving

    The North Surface Streets Project continues its street construction work this weekend at the intersection of Denny Way and Seventh Avenue. At 8 p.m. this Friday, Sept. 20, Wall Street will be closed at Denny Way. Southbound vehicles on Seventh Avenue North will have to turn right onto Denny Way. Denny Way will also be narrowed to one lane in each direction between Sixth Avenue North and Dexter Avenue North. These restrictions will end by Monday, Sept. 23 at 5 a.m.

    During the closure crews will pour new concrete roadway on Wall Street as part of our project's rebuilding of the intersection. This is the second of four weekends of paving in this heavily travelled intersection:

    • Sept. 13-16: Paving west side of Denny Way intersection [DONE]
    • Sept. 20-23: Paving Wall Street at Denny Way
    • Sept. 27-30: Paving east side of Denny Way intersection
    • Oct. 4-7: Follow-on paving work

    The rebuild of Seventh Avenue North reached a milestone this week when crews opened the brand-new sidewalk on the east side of the street between Harrison Street and Denny Way. Crews then closed the corresponding sidewalk on the street's west side. We are completing this work in phases to maintain routes for people driving, walking and biking in the area while conducting a total rebuild of three blocks of a major city arterial street.

    When work is complete in mid-2020 this three-block stretch of Seventh Avenue North will feature two lanes in each direction, dedicated bus lanes and new intersections at Thomas and John streets. You can follow construction's progress by signing up for our weekly construction emails.

  • South Dearborn Street set to reopen for Sept. 18 morning commute

    Demolition crews made quick work removing the section of the Alaskan Way Viaduct above South Dearborn Street, one of the structure's last remaining sections. As a result, the intersection of South Dearborn Street and First Avenue South will reopen Wednesday, Sept. 18 by 6 a.m. - much earlier than initially planned. By tomorrow morning First Avenue South will once again have two lanes in each direction and northbound Railroad Way South will also reopen. This video shows the work that took less than a week to complete.

    What’s next?

    Starting at 4 a.m. tomorrow morning, Alaskan Way will be narrowed to one lane in each direction near Marion Street so demolition teams can take down the one remaining span of viaduct along Seattle’s waterfront. Later this week, crews will stripe a bus-only lane on northbound SR 99 between South Spokane Street and South Dearborn Street. This lane existed during SR 99 tunnel construction and helps ensure reliable trips for King County Metro buses carrying about 30,000 passengers a day into downtown. The bus lane is scheduled to be in place by Sunday, Sept. 22 but the work is weather dependent. King County Metro's northbound buses will remain on temporary reroute until start of service on Sunday, Sept. 22.

    Caption: The two remaining sections of viaduct (in orange) at South Dearborn Street may not look big, but removing them is complex work due to the many underground utilities that criss-cross the area.

    SR 99 tunnel overnight closure this Friday, Sept. 13

    Both directions of the SR 99 tunnel will be closed 10 p.m. Friday, Sept. 13 to 8 a.m. Saturday, Sept. 14 for regular maintenance. The tunnel’s northbound direction will close again at 10 p.m. Saturday night and reopen by 8 a.m. Sunday, Sept. 15.
