State Route 20
(North Cascades Highway)

Elevation at high point, Washington Pass: 5,477 feet

OPEN

WSDOT re-opened State Route 20 (North Cascades Highway) on Friday, April 3. The low snow year meant the opening took only 3 weeks, and was the earliest opening since 2005, when the highway opened on March 10.

Watch for new snow or icy conditions during spring.

Avalanche hazard usually closes the highway sometime in late November / early December and it usually re-opens sometime between April to early May. Normal winter closure is between MP 134 (Ross Dam Trailhead) and MP 171 (Silver Star Creek). For updates, including re-opening information, conditions and the history of pass closure dates, visit Washington State Department of Transportation.
