District 10’s goal always is to open the mountain passes the Friday prior to Memorial Day weekend. We thank our crews for their hard work to meet this goal.
Our top goal is safety for the traveling public. Even though the pass is open, motorists still should be prepared for emergencies, as weather and road conditions can change
