Snoqualmie Pass Traffic: Spinouts, semi-truck accidents closed I-90 E for an hour

UPDATE: The eastbound lane of I-90 is re-opened after numerous collisions and spinouts, including several involving semi-trucks, shut down a stretch of Snoqualmie Pass for about an hour on Wednesday.

Despite the roadway being re-opened, snowfall will continue through the afternoon into the evening on the pass. Therefore, it’s possible that roads are closed once again depending on conditions and potential spinouts/accidents.

WSDOT teams don’t have a timeline for when the roadway will be cleared again, but the eastbound closure is impacting traffic all the way to the area of Hyak near milepost 55.

Additionally, WSDOT’s real-time traffic map shows significant stop-and-go traffic on I-90 heading westbound from the area of Stampede Pass to Hyak.

With snowy conditions in effect, the Snoqualmie Pass social media account offered the following warning to drivers heading through I-90 in the snow:

Traction tire requirements are in place for a reason. We need drivers to obey these requirements, chain up and take it slow. WSP is also out enforcing the requirements, but they can’t catch everyone.

This is a developing news story. An update and/or follow-up will be issued once further details are revealed.
