Interstate 90 over Snoqualmie Pass will remain closed Wednesday due to snow slides and debris on the highway, after a night of freezing rain and spinouts.

The Washington State Department of Transportation closed both directions of I-90, eastbound at North Bend and westbound at Ellensburg, early Wednesday and said it would evaluate when to reopen the roadway on Thursday.

Snow slides, rocks, collisions and about 30 trees are blocking the highway and make traveling treacherous, officials said.

Trooper Brian Moore tweeted Wednesday morning that troopers responded to 67 collisions overnight and roads continue to have layers of snow, sleet and freezing rain.

And the weather is not expected to get any better until late tonight, according to the National Weather Service.

About 7:30 p.m. Tuesday, State Patrol troopers reported on Twitter the freeway’s westbound direction from Ellensburg was closed due to freezing rain.

“Snow is sliding onto I-90 in a couple spots like sand from an hour glass,” state transportation officials tweeted. “Great night to #StayHome,” Moore added.

The interstate’s eastbound direction at milepost 47 was closed overnight due to multiple semitrucks spinning out, according to transportation officials.
