Transportation crews have reopened both directions of Snoqualmie Pass after being closed all day due to unsafe winter driving conditions, according to the Washington State Department of Transportation (WSDOT).

Crews reopened the pass’s westbound lanes late Thursday afternoon, and then reopened the eastbound lanes about two hours later around 6 p.m., according to the agency. Vehicles are required to have traction tires if they’re traveling westbound.


Earlier Thursday, the department said icy roads and sliding snow had made it unsafe for crews to do the work necessary to reopen the highway.

WSDOT spokesman Tom Pearce told members of the media Thursday morning that it would take “some time to get it cleaned up.”

I-90 through the pass was closed in both directions Wednesday after an ice storm downed trees and caused avalanches. According to the State Patrol, troopers responded to 67 collisions in the hours before the interstate was closed.
