The SR 99 /Alaskan Way Viaduct will close for its semiannual inspection this Saturday and Sunday, March 27 and 28, to ensure the structure remains safe for drivers. Both decks of the viaduct will be closed from Spokane Street through the Battery Street Tunnel from 6a.m. to 6 p.m. both days. During the closure, WSDOT and SDOT will coordinate maintenance and preservation work.
Expect increased congestion on all major north-south routes during the closure and plan accordingly – leave early, carpool, vanpool or take transit. Watch conditions at www.wsdot.wa.gov/traffic or get voice-activated driver information on 511.
