Road Conditions
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 the 1997 season. 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.
