Several semitrailers crashed in the westbound lanes of SR 18 Monday afternoon amid a sudden deluge of snow.
The crash happened just before the Issaquah-Hobart Road exit, according to WSDOT. Drivers should expect backups as crews tend to the wreck. At least one of the semi drivers was injured in the collision.
Although it was snowing around 2:30 p.m., the weather was expected to change to rain closer to the evening rush hour, possibly washing away some snow.
Highway Westbound is currently blocked by the collision.
