Major delays expected during 6-day closure on Snoqualmie Pass

Drivers could face major delays when crews reduce lanes on Interstate 90 over Snoqualmie Pass beginning this weekend.

Crews will close one lane in each direction for six days, starting Sunday, Oct. 14, as they prepare to open a new section of highway.

The Washington State Department of Transportation will reduce I-90 from a four-lane highway to a two-lane highway from 9 p.m. Sunday, Oct. 14, to 7 a.m. Friday, Oct. 19, to pave transitions between the old and new westbound and eastbound lanes.

More than 27,000 drivers travel over the pass every day. WSDOT officials are warning drivers to plan ahead.

Drivers can use online tools to decide the best time to travel over I-90 the week of Oct. 14. Visit to get the latest traffic information.
