NORTH BEND, Wash. -- Interstate 90 over Snoqualmie Pass reopened at 6:30 a.m. Monday after an overnight closure.

High winds and falling trees forced the closure of Interstate 90 in both directions across Snoqualmie Pass.

The Transportation Department closed the highway just before midnight Sunday for the 72 miles between North Bend and Ellensburg.

The department plans to assess conditions at dawn Monday to determine when the interstate could reopen. WSDOThas no estimated time for reopening. There's also snow and slush on the roadway.

Drivers diverting to Highway 2 over Stevens Pass found that chains are required. And the North Cascades Highway is closed by snow slides.

The I-90 closure was prompted by a semi-truck hitting a tree Sunday night 5 miles west of Easton. The Washington State Patrol says the injured driver was taken to a hospital in Ellensburg.

Troopers said there were four collisions on the east side of the pass.
