Yellowstone has five entrance stations, the North Entrance, Northeast Entrance, East Entrance, South Entrance and the West Entrance. It takes many hours to drive between these entrances, so be sure to check the status of roads at the entrance you intend to use. Most park roads are closed to regular vehicles from early November to late-April (see dates below) when the park switches to oversnow travel (snowmobiles and snowcoaches). The only road open year-round to automobiles 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 May. All dates listed below are subject to change depending on weather and budgetary restrictions.
The map below shows the status of park roads and road construction. Click on a road segment or colored icon for more detailed information. Conditions in Yellowstone can change quickly, especially during spring and fall. Updates to this map may be delayed, so check back often. Short-term road closures and delays may not be shown on this map.

Construction Projects Affecting Roads
Tower-Roosevelt to Chittenden Road

Expect construction and traffic pattern changes around the North Entrance. The entrance station will remain open. This project started in 2020 and will take two years to complete.
