Winter closures

Cayuse and Chinook passes close each winter due to high avalanche risk, poor road conditions, and no emergency response services within close proximity. Both highways closed to vehicle traffic for the season on Nov. 18, 2021. WSDOT and the National Park Service collaborate each spring to reopen the highways.
