The Washington State Department of Transportation (WSDOT) expects to begin clearing snow from SR 20, the North Cascades Highway, on April 10, 2017. Due to the large accumulation of snow through the mountains last winter the work to clear the mountain highway is beginning a month later than normal. In some places, the snow is 25 feet deep over the highway! As a result, the clearing work could take up to 8 weeks. For more information, visit the North Cascades Highway webpage.
