From WSDOT :
Seattle’s Battery Street Tunnel to close for four hours Saturday morning
Seattle’s Battery Street Tunnel will close in both directions this Saturday, Jan. 13 from 6 a.m. to 10 a.m. During this morning-only closure, drivers heading north on State Route 99 through Seattle will exit at Western Avenue. Southbound drivers traveling toward downtown will exit at Denny Way.
Southbound drivers will also be able to access the Alaskan Way Viaduct/SR 99 at the Elliot Avenue on-ramp as only the tunnel is closed.
The short closure will allow potential contractors to inspect the Battery Street Tunnel for decommissioning after the new SR 99 tunnel opens.
