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.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
