Fleet and Transportation

A group of bison crosses the Grand Loop Road in Hayden Valley. Visitor traffic stretches far back from the animals, causing a traffic jam.
Yellowstone's historic road corridors, abundant wildlife, and increasing visitation are a challenging combination.

NPS/Frank

Yellowstone National Park has 310 miles of paved road and our developed areas are an average of 30 miles apart. Just getting around Yellowstone takes considerable time, adding challenges to daily operations, and the creation of greenhouse gas emissions through burning of fossil fuels. Yellowstone‘s NPS fleet has over 500 vehicles for various purposes from commuting to plowing snow to moving earth.

Managers continue to look for opportunities to be more fuel-efficient through vehicle technology and operation in order to reduce greenhouse gas emissions. This begins with National Park Service policy to maintain or reduce the number of vehicles in our fleet. Yellowstone's fleet management plans include using more fuel efficient vehicles, and choosing the right vehicles for the job. Using the best technology available will help provide opportunities that enable and encourage greener transportation.

 
 

2018 Sustainability Report on Fleet and Transportation

Traffic jams are all too common in Yellowstone National Park. Whether it’s caused by visitors stopping to see a bear, bison strolling down the highway, or ongoing construction projects, it’s rare to pass through without having to stop for at least 10 minutes. These stops can unnecessarily increase greenhouse gas (GHG) emissions from transportation.
