Beginning at 10:30 PM this Thursday, September 5, the Marion St pedestrian bridge across Alaskan Way will close so crews in charge of demolishing the Alaskan Way Viaduct can remove the bridge’s span over Alaskan Way and haul it away. Alaskan Way will close Thursday night at 10 PM until Friday morning at 5 AM as part of this work.


This work will affect traffic on Alaskan Way and ferry passengers heading to and from Colman Dock. Plan ahead and give yourself extra time if traveling through the area.

After the old bridge is gone, uniformed police officers will manage intersections on Alaskan Way to ensure ferry passengers can safely cross. Officers will remain in place until a new, temporary pedestrian bridge opens along with the first section of the new Colman Dock ferry terminal.


Alaskan Way will narrow to two lanes between starting at Marion St and continue further south where demolition work continues.


During the demolition across from the ferry terminal, several nearby streets remain open. Pedestrians can use Columbia St, Madison St and Yesler Way. People with disabilities will continue to use the existing street-level elevators at Marion St to reach the upper level of Colman Dock until new elevators at Pier 50 near the passenger-only ferry terminal are open.

Millions of ferry passengers have walked the Marion St pedestrian bridge to and from Colman Dock, but after decades of operation, this well-traveled path is finally being removed. Demolition teams are now removing one of the last remaining double-deck sections of the Alaskan Way Viaduct.


Demolition of the Alaskan Way Viaduct is close to 90% complete. Removing the old Marion St bridge and the remaining viaduct at Marion St are critical steps toward reaching the demolition finish line.
