Third Debris Slide in a Week Blocks I-90 Eastbound Near North Bend, Causing Traffic Delays

Multiple Debris Slides Disrupt Eastbound I-90 Near North Bend

A third debris slide within a week has impacted eastbound Interstate 90 just past North Bend, Washington. At approximately 7:30 a.m. on Monday, the Washington State Department of Transportation (WSDOT) reported closure of the two right lanes at milepost 36 due to the slide.

The left two lanes remain open to traffic despite erosion along the roadway edge caused by the slide. According to the Washington State Patrol (WSP), the debris came down the hillside adjacent to the freeway. Emergency crews are en route to assess the stability of the slope.

Authorities urge drivers to exercise caution and anticipate possible delays in the affected area. The recurring slides have raised concerns over road safety and traffic flow along this busy route over Snoqualmie Pass.

This week’s slide follows two earlier incidents on the same stretch:

1. On December 8, a significant debris flow closed eastbound lanes overnight near milepost 34.
2. On December 10, debris blocked the freeway between Snoqualmie and North Bend for over 24 hours.

The latest slide coincides with an atmospheric river event hitting the Pacific Northwest, which is expected to increase rainfall in the region. Meteorologists warn that the additional rainfall may cause flooding in already saturated rivers and raise the likelihood of further landslides.

KING 5 has issued a First Alert for this weather event. The news station’s Weather Team is actively monitoring conditions to provide updates aimed at protecting lives and property. Motorists are advised to stay informed and plan extra travel time as conditions continue to evolve.

WSDOT and WSP continue close monitoring of the hill slopes and road conditions to mitigate additional disruptions. Travelers should remain vigilant on I-90 and consider alternate routes if possible during this unsettled period.
