Highways across Washington will be jammed beginning Wednesday as drivers travel for the Thanksgiving holiday and wintry weather makes driving conditions more challenging.

Travelers should expect lengthy delays on Interstate 90 and Interstate 5, and long wait times at ferry docks and the border crossing between the United States and Canada, according to the Washington State Department of Transportation (WSDOT).

Weather may add further delays. The National Weather Service is forecasting a shift in the weather Wednesday to rain, wind and snow in the mountain passes by Friday.

In Seattle, public transportation will operate on modified schedules.

Sound Transit‘s Link light rail and express buses will run on a Sunday schedule on Thanksgiving Day. On Friday, light rail will run on a Saturday schedule and express buses will run on a typical weekday schedule.

King County Metro will provide bus service on a Sunday schedule Thanksgiving Day. Metro named the day after Thanksgiving Mark McLaughlin Day, after the Metro employee who was killed while driving Route 359 over the Aurora Bridge in 1998. Buses will run on a reduced weekday schedule Friday.

Meanwhile, drivers in Spokane, Whitman, Adams, Grant and Kittitas counties should be extra cautious. Washington State Patrol troopers will be running an emphasis patrol through Sunday, focusing on holiday travelers and on fans heading to Pullman for the Apple Cup on Friday.

WSDOT encourages drivers to plan ahead for smoother travel. Complete estimated travel times, based on historical information, are available on the agency’s website.
