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
The road between Tower-Roosevelt and Chittenden Road will be completely closed until May 2022. (In 2021, the full closure will be between Tower Fall and Chittenden Road.) Specific areas on each side of this closure will be open for select time periods:
- On the Canyon Village side of the closure: Currently closed; no estimate on reopening. Trails to the top of Mount Washburn are also closed.
- On the Tower-Roosevelt side of the closure: Closed all of 2021. Tower Fall, the Tower General Store, Tower Fall Campground, and Calcite Springs will be open and accessible from Tower-Roosevelt between June 4–September 26, 2021. In the winters, Tower Fall and trails in the vicinity will be open for skis and snowshoes, snow-permitting, from early November through March (follow all closure signage posted at Tower-Roosevelt). Traffic from Tower-Roosevelt will be turned around at Calcite Springs May 7–June 4, 2021; and September 26–November 8, 2021. There will be no access to the trails for Mount Washburn from the Tower-Roosevelt side of the closure.
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.
