Traveler Information

Beartooth Highway

The Beartooth Highway is currently CLOSED for the season.

The road, which closes each winter because of excessive snow and adverse winter conditions, typically opens by the Friday of Memorial Day weekend.

Snow levels vary and drifts can be as high as 26 feet in the higher elevations.

MDT is responsible for the highway to the Montana/Wyoming border, where the National Park Service takes over maintenance responsibilities through Wyoming, back into Montana and into Yellowstone Park. MDT and NPS coordinate closely in keeping the road open throughout the summer.

Opening the Beartooth Highway is a huge undertaking - check out these videos of our crews working hard to get it open for the 2021 season. During the time that crews were working to open the road, we posted a new video frequently.

A map of Beartooth highway is provided to assist with descriptions and landmarks mentioned in the videos.
