Alaskan Way Construction

The work zone on Alaskan Way has expanded to Pike Street. Similar to construction underway between S King and Marion streets, intersecting east/west streets will remain open and pedestrian access will be maintained. Businesses with mid-block vehicle driveways will be provided a route adjacent to the work zone. Initial activities include establishing work zones, mobilizing equipment, locating utilities, surveying, delivering materials, and breaking pavement for excavation and utility installation. View our construction flyer for more detail on work expanding to Pike Street.

Pier 58

Pier removal was completed in February 2021. The rebuild is anticipated to begin in 2022 and take approximately two years to complete. 

Union St Pedestrian Bridge and Elevator

Construction of a new pedestrian bridge, stair and elevator between Western Ave and Alaskan Way began on March 17, 2021. The existing staircase at Union St connecting Western Ave with Alaskan Way will be closed until the project is complete. Pedestrians will be able to access Alaskan Way from University St or the Pike St Hill Climb. The Union St Pedestrian Bridge project will build a new connection with an elevated walkway, elevator and staircase; and make improvements to the Western Ave intersection. This new connection to the waterfront will provide significant accessibility improvements and is planned to open in late 2022.
