General Road Construction Information
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.
