Clearing the North Cascades Highway

Washington State Department of Transportation (WSDOT) maintenance crewmembers on both the east and west sides of the North Cascades mountain passes are in the process of clearing snow from 37 miles of the highway, including Rainy and Washington passes. Work started on Monday, March 30.

State Route 20, the North Cascades Highway, is the northernmost route across the Cascades in Washington. This scenic byway is part of the Cascade Loop, a 400-mile driving tour through the Cascades.
WSDOT closes the North Cascades Highway in the winter when snow and avalanche danger threatens the safety of drivers and maintenance crews. On average, the highway is closed between late November and early December and reopens in the spring between late March and early May.



Clearing the North Cascades Highway is a significant effort each year. WSDOT crews will work 10-hour days, Monday through Thursday, through
April.

While it’s impossible to predict exactly when they will have it open – due to weather (the Cascades have gotten 32 more inches of snow in the last 21 days), avalanche danger, equipment breakdowns, and crew health – they are hoping they can match last year.

The highway reopened May 1 last spring and was closed for the season on Dec. 11. The cost to reopen the highway each spring typically runs from $200,000 to $250,000. WSDOT requires that climbers and skiers engage in frequent and varied spring skiing and climbing trips to make this a good investment :) .

. . . Looking good! On Tuesday morning, this is the Lloyd Logging D-8 caterpillar cutting a pocket above the shoulder, below an avalanche chute along Cutthroat Ridge, so if any more snow slides, it won't end up on the roadway.

While clearing snow off SR 20, the crews see a lot of different wildlife. This time it was a rabbit. They said it's actually not uncommon for them to see rabbits along the snow-covered highway. They said that this particular rabbit was charging the snowblowers, and was following them as they worked.

Little (pre-powdered) snow donuts rolled their way down the hill and landed near our maintenance crews clearing snow from the highway.

  1. Thanks for sharing updated information about our spring clearing of the North Cascades Highway.

    I assume you already know about our e-mail updates for the North Cascades Highway, but if you don't, you can easily subscribe here www.wsdot.wa.gov/emailupdates. Jeff Adamson is sending updates out twice a week right now.
