General Road Construction 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, park road repair crews will be working in other areas of the park throughout the seasons.

Yellowstone reconstructs its roads during the spring, summer and fall seasons, which means you will likely encounter delays depending on your destination. It's a good idea to check with our visitor centers or entrance stations for current information and possible delays.
