What to expect

On Monday, Sept. 26, one southbound lane of First Avenue South at South Dearborn Street will be temporarily closed to create a work zone in the center of First Avenue South. Crews will be removing temporary asphalt and pouring new concrete in the center of the roadway. No turns will be restricted during this temporary lane configuration.

South Charles Street is open to traffic in a temporary configuration providing a new east-west connection between First Avenue South and Occidental Avenue South. No left turns are permitted from southbound First Avenue South onto South Charles Street, or from South Charles Street onto southbound First Avenue South. South Charles Street will be closed for approximately 45 days later in fall 2022 for final paving. 

Travel lanes are shifted on Alaskan Way between South Dearborn Street and South King Street for drainage and pavement work. The left turn from northbound Alaskan Way to Pier 46 at South King Street is temporarily restricted. Drivers should expect ongoing lane shifts and turn restrictions on this block of Alaskan Way into fall 2022. 

Construction is ongoing on the east side of First Avenue South between South Charles Street and South Dearborn Street. Occasional short-term sidewalk or lane closures and detours may occur to provide safe space for construction crews and equipment.

The project completes road work around the south portal of the SR 99 tunnel, near Seattle's stadiums.
