Snoqualmie Pass Traffic Conditions
As of March 11, 2026, traffic on Snoqualmie Pass remains heavily congested due to snow and slush on the roadway, resulting in multiple crashes. Both directions of I-90 were initially closed following these incidents, causing significant delays for travelers.
Westbound I-90 has since reopened after being closed at Easton, while eastbound lanes were reopened by 3 p.m. after being shut down at North Bend. The distance affected by the traffic shutdown was approximately 40 miles, causing considerable disruption for drivers.
Authorities have advised that traction tires are necessary for all vehicles traveling over the pass, and oversized vehicles are prohibited in order to enhance safety on the roads. The situation has been exacerbated by a Blizzard Warning that is set to take effect for the Washington Cascades from 6 p.m. Wednesday through 5 a.m. Thursday.
Earlier in the day, around 2:30 p.m., several semi-trucks spun out, contributing to the hazardous driving conditions. Although eastbound traffic has resumed, no estimated reopening time has been provided for westbound traffic at Easton.
In addition to Snoqualmie Pass, US 2 Stevens Pass was also closed for several hours but has since reopened. Drivers heading over Stevens Pass are required to carry chains due to the winter weather conditions.
Officials have noted that clearing collisions and making the roadway safe can take time, especially when multiple vehicles are involved or if heavy snow is falling. “The safest option may simply be to delay your trip until the pass reopens and conditions improve,” they advised.
Historically, Snoqualmie Pass is known for its challenging winter weather, which often creates dangerous driving conditions. As always, travelers are encouraged to stay updated on the latest road conditions and to exercise caution when traveling in winter weather.
Details remain unconfirmed regarding the full extent of the traffic situation and any additional closures that may arise as the weather conditions evolve.
