Park Roads


The only road generally open year-round to automobiles is from the North Entrance at Gardiner, Montana through the park to Cooke City, Montana (via Tower Junction). Most park roads are closed to regular vehicles from early November to late-April, and are open to limited oversnow travel (snowmobiles and snowcoaches) from mid-December to mid-March. When open, roads are not gated at night and people may enter/exit the park 24 hours a day, seven days a week.

Yellowstone has five entrance stations, and it takes several hours to drive between them. Anticipate possible road closures, and check the road status of the entrance you intend to use before traveling.

Traffic Delays

It's important to be aware of all planned road improvement projects, as they can cause major traffic delays throughout the park. Drive slowly through construction zones and be alert to workers, heavy equipment, wildlife, and other hazards. The following road improvement projects in Yellowstone will cause traffic delays:

Location: East of Mammoth Hot Springs on the Grand Loop Road between Mammoth Hot Springs and Tower-Roosevelt
Access: Expect up to 20-minute delays from April 11 - June 30, 2023.
Improvements: This project includes the reinforcement of bridge approaches on the Gardner River High Bridge to allow for upcoming improvements to the Yellowstone River Bridge.

Location: Nearly 10 miles north of the South Entrance on the South Entrance Road
Access: Expect up to 20-minute delays between May – Oct. 31, 2023. Additionally, there may be overnight closures before June 30 (check the Yellowstone road status map above). Work will begin summer 2023 and continue through fall 2024.
Improvements: This project includes the removal and replacement of the Lewis River Bridge. The existing bridge will be removed, and a new bridge will be constructed immediately downstream, with additional parking and viewing opportunities.

Location: East of Tower Junction between Lamar Canyon and the Northeast Entrance
Access: Expect up to 30-minute delays beginning early summer 2023 through fall 2023. A short section in Lamar Canyon will temporarily close from 7-9 p.m. on June 5,7,8,12,14 and 15. 
Improvements: This project includes the completion of work to address flood-damaged areas of the Northeast Entrance Road. Construction will include completion of a two-lane realignment in Lamar Canyon, paving a second lift north of the Trout Lake Trailhead, stabilization of streambanks adjacent to the road, and work in the Pebble Creek Campground and Warm Creek Picnic Area. Additionally, some guardrails, culverts, and other drainage structures will be replaced.

Location: Grand Loop Road between Old Faithful and West Thumb
Access: Expect up to 30-minute delays between May – Nov. 2, 2023.
Improvements: This project includes the rehabilitation of over 20 miles of the Grand Loop Road between Biscuit Basin and Grant Village, including Old Faithful and West Thumb. This is one of the most heavily traveled road corridors in the park. Construction will include repaving the roadway and replacing guardrails, culverts, and other drainage structures.

Location: Near Tower Junction along the Northeast Entrance Road
Access: Expect occasional and short traffic delays during 2023. Work will begin in summer 2023 and continue through fall 2026. Hiking trails in the area may close temporarily (visit the Backcountry Situation Report for details).
Improvements: This project includes the replacement of the structurally deficient Yellowstone River Bridge. A new bridge upstream will replace the existing 604-foot-long bridge to preserve year-round access to/from the Northeast Entrance and communities of Silver Gate/Cooke City, Montana. Additionally, construction will include new pullouts and paved parking areas, and the Yellowstone River Picnic Area will be expanded.


Additionally, chip sealing occurs every summer and preserves Yellowstone's roads. Check the park's live road map (above) to see where chip sealing is scheduled to occur and plan for delays of up to 30 minutes. Drive slowly and maintain the recommended speed limit on chip seal pavement to reduce the risk of loose gravel damaging cars or windshields.
