Wyoming's diesel rate is 24.0¢/gal (2Q 2026). Cheyenne is Wyoming's primary freight hub at the I-25/I-80 interchange and handles significant cross-country freight as one of the highest-elevation points on the I-80 corridor.

Major Wyoming Trucking Routes

I-80 (Salt Lake City UT–Cheyenne–Omaha NE, primary east-west), I-25 (Denver CO–Cheyenne–Casper–Montana), I-90 (South Dakota–Gillette–Buffalo–Montana), US-30 (Evanston–Rock Springs–Rawlins, secondary I-80 parallel)

Wyoming's energy sector — coal from the Powder River Basin (largest coal producing region in the US), oil and natural gas from the Pinedale/Jonah fields — generates enormous heavy freight volume.

Wyoming's diesel rate is 24.0¢/gal.
Who administers IFTA for Wyoming-based carriers?
Wyoming IFTA is administered by the DOT. File quarterly at dot.state.wy.us.
What are the challenges of I-80 through Wyoming?
I-80 through southern Wyoming, particularly the Laramie–Rawlins stretch at 7,000+ feet, is one of the most dangerous winter driving routes in the US. High winds, blowing snow, and ice cause frequent closures. WYDOT closes I-80 more frequently than almost any other interstate — check wyoroad.info before dispatching.
What coal freight moves through Wyoming?
Wyoming's Powder River Basin produces over 40% of US coal. Unit coal trains (not trucks) dominate the bulk movement, but truck freight serves mines with equipment, explosives, tires, and lubricants. Casper and Gillette are the primary energy freight hubs. Permian-style oil growth in the DJ Basin near Cheyenne is adding new tanker and equipment freight.
