Crews will close the westbound lanes of Interstate 90 near the Snoqualmie Pass Summit on Sunday morning to remove several trees.
Drivers need to plan for delays of up to two hours, a news release from the Washington State Department of Transportation said.
The westbound lanes will close at milepost 52 from 8:30 to 10:30 a.m. Sunday. Drivers will still be able to access the summit of Snoqualmie Pass from the west at milepost 54.
This work is weather dependent and subject to change, the department said.
