  • Alaskan Way Viaduct to close Oct. 6-9 for twice-yearly inspection

    Update: The closure has ended and the Alaskan Way Viaduct has reopened in both directions.

    Alert to Seattle drivers

    The Alaskan Way Viaduct will close this weekend, Oct. 6 – 9, for the twice-yearly inspection designed 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.

    Closure details:

    • SR 99 closed between South Spokane Street and the north end of the Battery Street Tunnel.
    • The northbound roadway will close at 11 p.m. Friday, Oct. 6 and reopen at 5 a.m. Monday, Oct. 9.
    • The southbound roadway will be closed from 5 a.m. to 6 p.m. on both Saturday and Sunday, Oct. 7-8. 
    The duration of this semiannual closure is a little different from past inspections. The northbound SR 99 closure starts earlier and lasts longer than typical inspection closures. This will allow the SR 99 tunnel contractor Seattle Tunnel Partners time to complete tunnel-related work.
    We conduct these closures every October and March so engineers can closely inspect the elevated portion of SR 99. Drivers through Seattle should plan ahead and be prepared for additional congestion. Drivers can check WSDOT’s travel tools and follow WSDOT Traffic on Twitter for information about traffic in the Puget Sound region.
