Alaskan Way Construction Expanding to Pike Street

Starting as early as December 9, the work zone on Alaskan Way will expand incrementally north 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.

Columbia Street

We began transforming Columbia Street into a two-way corridor with transit lanes and improved sidewalks in August 2019. Other activities include installation of new underground utilities. Columbia Street will open on Saturday, February 22, 2020.
