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. Activities include mobilizing equipment, locating utilities, surveying, delivering materials, breaking pavement for excavation and utility installation and striping and paving. 

Pier 58

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