Avalanche control work will start on Interstate 90 at 8 p.m. tonight, prompting inevitable delays for drivers heading in both directions.
Washington State Department of Transportation crews will shut down eastbound lanes near Gold Creek at milepost 56. Westbound lanes will be closed near Price Creek at milepost 61.
There is no estimated time for I-90 to reopen.
UPDATE: The avalanche work is complete and normal traffic is resuming.
