The Washington State Department of Transportation is closed in both directions of SR 99 between South Spokane Street and Valley Street until 5 a.m. Monday, Aug. 25. Crews will reopen SR 99 south of the Battery Street Tunnel just before the Monday morning commute; however, the highway will remain closed through the tunnel to Valley Street until 5 a.m. Wednesday, Aug. 27.

“We need Seattle commuters to plan ahead for this closure,” said Dave Sowers, deputy administrator for the WSDOT Alaskan Way Viaduct Replacement Program. “The section of 99 we’re closing Monday and Tuesday is shorter in length than what we’re closing that weekend, but it has the potential to create longer backups and delays both on city streets and I-5.”
