The Seattle Department of Transportation advises that the westbound lanes of the Spokane Street Viaduct will be closed just west of I-5 for three nights, August 16-18. During these closures, southbound traffic exiting I-5 will be detoured to the S. Forest St. exit. Northbound traffic and westbound traffic from Columbian Way on Beacon Hill will be detoured to surface streets at 6th Ave. S. Drivers on southbound Highway 99 will still be able to access West Seattle as usual.

On August 15, the right lane of the westbound Spokane Street Viaduct will be closed overnight. The I-5 westbound ramps will remain open.
