Park still cleaning Yellowstone’s biggest road fuel spill in nearly 20 years

YELLOWSTONE — The road between Mud Volcano and Fishing Bridge Junction remains closed as the park service and the Wyoming Department of Environmental Quality work to clean up the largest roadside fuel spill in Yellowstone National Park in nearly 20 years.  

The spill was caused after a tandem trailer on a commercial motor vehicle overturned, releasing approximately 3,000 gallons of unleaded fuel.

A large hole in the road was excavated to locate the extent of the spilled gasoline, remove the contaminated soil, and ensure cleanup. The hole is 100 feet wide by 100 feet long by 10 feet deep. Currently, there is no evidence that gasoline entered the Yellowstone River. 

Excavated materials contaminated with gasoline will be removed from the park and disposed of at an appropriate facility.


Due to the prolonged road closure between Mud Volcano and Fishing Bridge Junction, consider alternate routes.

Currently, Mud Volcano is only accessible from the north, and Fishing Bridge Junction is only accessible from the south and from the East Entrance
