Park Roads

The map below shows the status of park roads and road construction (which occurs every year when weather allows). Click on a road segment or colored icon for more detailed information.

Most park roads are closed to regular vehicles from early November to mid-April (see dates below) when the park switches to oversnow travel (snowmobiles and snowcoaches). The only road open year-round is from the North Entrance at Gardiner, Montana, through the park to Cooke City, Montana, (via Tower Junction). Travel east of Cooke City (via the Beartooth Highway) is not possible from late fall to late spring.

Conditions in Yellowstone can change quickly, especially during spring and fall. Updates to this map may be delayed, so check back often. Temporary road closures and delays are always possible and may not be shown on this map.
