Alaskan Way Viaduct to close the weekend of Oct. 8 and 9

Posted on Oct 3 2016 3:02 PM

From 6 a.m. to 6 p.m. Saturday, Oct. 8, and Sunday, Oct. 9, both directions of SR 99 will be closed between South Spokane Street and the north end of the Battery Street Tunnel for a semiannual inspection. WSDOT closes the viaduct for inspection every fall and spring so WSDOT engineers can thoroughly examine the aging roadway and make sure it remains safe for drivers.

Also, between 6 a.m. and 3 p.m. Saturday, Oct. 8 only, crews working north of the Battery Street Tunnel will close SR 99 in both directions from the tunnel to Valley Street. Northbound drivers can access SR 99 at Valley Street.
