A powerful winter storm has forced the closure of eastbound Interstate 90 (I-90) at Snoqualmie Pass, leaving travellers stranded and disrupting traffic through one of Washington’s most critical mountain routes. The Washington State Department of Transportation (WSDOT) announced the closure on Thursday afternoon, citing dangerous conditions, multiple crashes, and rapidly accumulating snowfall.
Hazardous Road Conditions Lead to Closure
According to WSDOT, heavy snow continues to fall in the Cascade Mountains, creating low visibility, icy roads, and treacherous driving conditions. Snowploughs are actively working to clear the highway, but multiple vehicle spinouts and collisions have made reopening uncertain.
🚨 Eastbound I-90: CLOSED between Denny Creek and Snoqualmie Pass Summit due to crashes and worsening road conditions.
🚨 Westbound I-90: Remains open, but drivers are required to use traction tyres, and large trucks must chain up.
🚨 No Estimated Time for Reopening: Road crews are working around the clock, but the closure could extend into the night depending on snowfall rates.
Why Is This Storm So Dangerous?
Meteorologists warn that the storm system moving through the Pacific Northwest is bringing intense snowfall, which could dump over a foot of snow in the Cascades. Winds are also picking up, leading to blowing and drifting snow that makes driving nearly impossible.
How This Closure Impacts Travel
❄ Traffic Delays: Drivers heading eastbound on I-90 are being turned around, while westbound travellers face slow-moving conditions.
❄ Flight Disruptions: Seattle-Tacoma International Airport is also reporting delays and cancellations due to the storm.
❄ Freight and Supply Chain Issues: The closure of this major transportation route could impact deliveries across the state.
What Drivers Need to Know
✔ Avoid travel through Snoqualmie Pass until conditions improve.
✔ Check WSDOT updates before heading out – additional closures are possible.
✔ Carry emergency supplies if you must travel, including warm clothing, blankets, food, water, and tyre chains.
✔ Drive slowly and leave extra space between vehicles if on the road.
When Will Snoqualmie Pass Reopen?
At this time, there is no estimate for reopening eastbound I-90. WSDOT crews are assessing the situation, and updates will be provided throughout the evening. Until conditions improve, travelers should plan alternate routes or delay their trips.
