Marching south: demolition approaches the southern end of the viaduct

Posted on Jun 13 2019 11:10 AM

The southern stretch of the Alaskan Way Viaduct was saved for last, and now its time is coming. WSDOT's contractor Kiewit is preparing to begin work on removing the section of viaduct that remains between Yesler Way and South Dearborn Street.

Early this Friday morning Alaskan Way will be narrowed to one lane in each direction between South King Street and South Dearborn Street. Crews will use this space to establish a work zone so they can safely begin demolition later this month on the viaduct adjacent to Railroad Way South.

Alaskan Way is a busy arterial in this area and a key connection to SR 99. Travelers approaching downtown from the south this summer should plan for longer drive times, especially during peak commute periods and on weekends. Consider taking transit and the King County Water Taxi as a driving alternative. Access routes to Colman Dock will remain unchanged for the moment.

In July the contractor will add a second crew to the job of removing the viaduct's southern section. The plans for this work, including where that crew will start along the structure, are still being refined and we will share more information in the weeks to come. Drivers should expect that at some point streets connecting Alaskan Way to First Avenue South will close beneath the viaduct, and additional stretches of Alaskan Way will be narrowed. People traveling along Alaskan Way, especially to and from Colman Dock, should expect higher than normal congestion in the area through the end of August as we conclude work on one major component of the Seattle Squeeze.
