Introduction
Begin near Gillette's coal mines, which produce about 12% of U.S. electricity feedstock, then head north on I-90 and US-87 toward the Montana Hi-Line. The 450-mile trip typically takes 7 hours without stops, but plan for at least a day to enjoy the views. Use this guide to make the most of the journey.

Road Safety, Family Stops, and Fatigue Management
Wildlife crossing zones are common; dusk and dawn are high-risk times. Rest areas every 50 miles, but picnic areas at murals like Pompeys Pillar (Lewis and Clark's signature) make great breaks.
For kids, the Range Riders Museum in Miles City and the Yellowstone Art Museum in Billings offer cultural respite. For pets, National Forest trails near Ashland and the Tongue River Reservoir allow off-leash romps. Take turns driving and share the wheel; a 15-minute layover every 2 hours keeps you alert.
For hidden gems, try the ghost town of Kirby or the Pryor Mountain Wild Horse Range. Check this how to find the best stops and hidden gems between cities for more ideas.
Route Logistics and Infrastructure
Major highways: I-90 west from Gillette to Buffalo, then US-87 north to I-94 near Billings, then US-87 through Roundup and US-2 to Havre. Fuel stops every 50-70 miles; last cheaper gas before Montana is in Sheridan. Check road conditions via Wyoming 511 and Montana DOT.
- Interstate 90: 4-lane divided, speed limit 80 mph in Montana
- US-87: 2-lane, some passing lanes
- US-2: 2-lane, oil-rig traffic east of Havre
- No tolls on entire route
Natural Landscapes and Local Commerce
Rolling plains evolve into Bighorn Mountains at Sheridan, then the Tongue River Valley near Ashland. The Little Bighorn Battlefield (site of Custer's Last Stand) is 15 miles off I-90 near Crow Agency.
Local commerce thrives in ranching towns like Miles City (famous for its bucking horse sale) and Hardin. Try Basque chorizo in Buffalo, and huckleberry pie in Billings. These stops show how the region's heritage shapes its food and shops.
