See Yellowstone Road Map for reference points. There is also a link on every park web page to a fully resizable map of the park. See "View Park Map" on the lower, left side of the page.

Park Road Construction During the Seasons
Yellowstone reconstructs its roads during the spring, summer and fall seasons, which means you will likely encounter delays depending on your destination. To minimize delays, consult the maps below as you plan your drive into the park. Keep in mind, road work schedules change. Check at our visitor centers, or entrance stations for updates for current information on road construction and possible delays.More road information, including what roads are open during each season, see our Operating Hours and Seasons page. Call the 24-hour Current Road Report hotline at (307) 344-2117 for the latest information on conditions affecting roads within the park.

Motorcyclists are advised to slow down and use EXTREME CAUTION on loose gravel in areas of construction.

Traveling to Yellowstone All Summer:

Expect road improvement projects on many of the major travel routes to Yellowstone Park entrances from Montana and Wyoming.

Projects include Chip-seal and/or fog-seal to extend road surface life. Expect 30-minute delays and the use of pilot vehicles. Be aware of construction workers and equipment. MOTORCYCLISTS USE CAUTION.

General Information
Road construction is perennial in Yellowstone National Park. In general, park roads have either been recently repaired or reconstructed, or are scheduled for repair or reconstruction. Approximately 80% of main park roads (about 185 mi or 295 km) are in a structurally deficient state, with poor quality road bases failing under the weight, speed, and volume of modern traffic for which they were not designed. Harsh winter weather and short construction seasons provide additional challenges.

These needs are now being addressed under a 20-year, $300 million Federal Lands Highway Program for Yellowstone National Park. In addition to the major construction addressed below, park road repair crews will be working in other areas of the park throughout this and subsequent seasons. Thank you for your patience with our road construction efforts.

Other road closures or delays are possible. For current road information, call: 307-344-7381.

Additional construction zones and schedules may be announced as construction contracts are awarded.
