SEATTLE  — Transportation officials say Interstate 90 will remain closed at Snoqualmie Pass for most of Thursday.

The roadway is closed for an 80-mile stretch from North Bend to Ellensburg due to heavy snow fall, trees leaning over the roadway and high avalanche danger.

Washington State Department of Transportation crews worked throughout the night on avalanche control work, as well as clearing the roadway of snow, crashes and motorists in trouble.

Officials say they will evaluate conditions Thursday evening to determine when the pass can reopen.

Snoqualmie Pass is about 54 miles east of Seattle and is the major east-west passageway over the Cascade Range.

Stevens Pass was closed for some of the morning for avalanche control work. White Pass on U.S. 12 is open.
