Viaduct inspection closure complete, highway is open
SAT 4:30 PM UPDATE: Inspection complete and viaduct is open. No closure on Sunday.
The Alaskan Way Viaduct will close the weekend of March 24–25 for the twice-yearly inspection WSDOT conducts to keep the aging roadway safe for everyday use. Both directions of State Route 99 will close between South Spokane Street and the north end of the Battery Street Tunnel.
- SR 99 closed between South Spokane Street and the north end of the Battery Street Tunnel.
- Highway closed 6 a.m. - 6 p.m. Saturday, March 24 and 6 a.m. - 6 p.m. Sunday, March 25.
Travelers will need to take an alternate route during the closure weekend and expect possible delays in the area. If inspection work finishes early and the road can reopen before 6 p.m. Sunday, we will update this post and share via our Twitter account.
These closures are conducted every March and October so engineers can closely inspect the viaduct. Take advantage of WSDOT’s travel tools and follow WSDOT Traffic on Twitter for updates on traffic in the Puget Sound region.
