"Another Bridge" On 1st Ave

SEATTLE (July 18, 2022) – Construction of the Marion Street pedestrian bridge begins this week. This will enhance the experience for the millions of annual users who walk and roll to and from Colman Dock.



The new bridge will provide a direct connection between First Ave and Colman Dock on Marion St. It will meet the existing bridge at Western Ave, span over the recently completed Alaskan Way roadway, and tie into the second level of the Colman Dock Entry Building. The current temporary bridge on Marion St, Western Ave and Columbia St has been providing this link since the Alaskan Way Viaduct was demolished and will remain open until completion of the new bridge.


“We look forward to providing a clear connection to the ferry terminal which will help facilitate navigation in this busy area,” says Angela Brady, Director of the Office of the Waterfront and Civic Projects. “The new bridge will offer a more pleasant and safe experience to commuters and will provide a unique architectural vantage point upon which to enjoy Seattle’s new waterfront.”


The new bridge over Alaskan Way will be a cast-in-place post-tensioned concrete bridge with architectural details. It will provide a wider pathway – 16-feet wide instead of the original 13-feet – and have better lighting both above and below the bridge. This new lighting will improve safety and nighttime travel along the waterfront.


Alaskan Way and Marion St will remain open during this construction with periodic overnight lane closures. Sidewalk detours will be in place on the south side of Marion St and the east side of Alaskan Way between Columbia and Marion streets. Typical work hours will be 7 AM to 4 PM Monday through Friday. The City will be working directly with adjacent properties to notify them of upcoming work and access changes.


Flatiron is the contractor for this project, and the construction contract is approximately $6.3M. The project is funded jointly by the City and by the Washington State Department of Transportation (WSDOT). The city closely coordinated with WSDOT to sequence work in this critical transportation hub to create efficiencies for construction of the new Alaskan Way roadway, the Marion St Bridge and Colman Dock, all while maintaining access to and from the ferry terminal.


The new bridge is anticipated to be open in Summer 2023, and the project complete by late 2023, including removal of the temporary pedestrian bridge.
