OLYMPIA – Heading out for one last summer holiday weekend? Planning ahead could be the key to smooth sailing whether on land or sea.

Travelers can use the Washington State Department of Transportation’s traffic volume charts this holiday weekend to “know before they go” and help time their travel on key routes. In particular, this year, holiday congestion is expected on Interstate 90 near Snoqualmie Pass – especially westbound traffic.

I-90/Snoqualmie Pass

Bridge deck repairs in the westbound lanes of I-90 between the summit of Snoqualmie Pass (milepost 52) and North Bend (milepost 34) will not be complete by Labor Day as initially hoped. This means only two of three lanes will be open for drivers heading westbound. The lane closures are needed because portions of the bridge decks have been removed and traffic can’t be shifted back on those decks until new concrete is placed and cured. Drivers will also encounter lane closures and traffic shifts through the Cle Elum area (milepost 86) due to work to replace old pavement with new concrete lanes.

Know before you go

To ease congestion statewide, WSDOT suspends most state highway construction work during the holiday weekend starting Friday, Sept. 1. On Labor Day, Monday, Sept. 4, the State Route 520 bridge toll will be on holiday rates, while the Interstate 405 express toll lanes will be free and open to all drivers.

Washington State Ferries passengers should expect heavier traffic during the holiday weekend and reservations are strongly recommended for the Anacortes/San Juan Islands; Anacortes/Sidney, British Columbia; and Port Townsend/Coupeville ferry routes.

Travelers planning to avoid highway congestion by traveling via train, personal aircraft or transit also should factor the holiday into their plans:
