What to expect

South Charles Street is open to traffic in a temporary configuration providing a new, direct east-west connection between First Avenue and Occidental Avenue. The temporary configuration will function as Railroad Way South did, with no left turns from southbound First Avenue onto South Charles Street or from South Charles Street onto First Avenue southbound. South Charles Street will be closed for a second 45-day window later in the summer. 

Crews also shifted traffic on Alaskan Way South between King Street and Dearborn Street to the west. Northbound traffic turning left into the terminals will be detoured, and transit will merge into general traffic. This is the first of two temporary traffic configurations that are expected to be in place for a total of 90 days.

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 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.
