Sheridan to Butte Road Trip: Ultimate Guide via I-90/US-87

On the 350-mile journey from Sheridan, Wyoming to Butte, Montana, you trace the path of the Bozeman Trail, a historic route used by miners and settlers. The drive largely follows I-90 West and US-87 North, crossing the Bighorn Mountains and the high plains of southern Montana. Average driving time is 5.5 hours without stops, but plan a full day to savor the landscapes.

Quick Facts

Fuel up in Sheridan before heading west on I-90. Gas stations are sparse between Ranchester and Lodge Grass, so plan your stops. For best prices, fill in Sheridan or Buffalo, WY. The route climbs over the Bighorn Mountains (elevation ~9,000 ft at Powder River Pass) then descends into Wyoming's Powder River Basin.

• Key fuel stops: Sheridan (multiple brands), Buffalo (exit 299), Hardin, MT (exit 495), Billings (many options), Butte (end).
• Average gas price: $3.50–$4.00/gal. Slightly cheaper in Wyoming.

Road Quality and Safety

I-90 is well-maintained, but watch for wildlife (deer, antelope) especially at dawn/dusk. In winter, carry chains and check road conditions via WYDOT and MDT. The Bighorn section has steep grades; use lower gears. Cell service is spotty between Sheridan and Buffalo.

• Emergency: Dial 911 from any cell.
• Tow services: AAA preferred; limited coverage in remote areas.

Both routes are pet-friendly – many motels in Sheridan, Buffalo, and Butte accept dogs. Rest stops every 30–50 miles on I-90: Buffalo Rest Area, Ranchester Rest Area, and Hardin Rest Area.

Fatigue Management

Take a 15-min break every 2 hours. Use rest stops with picnic tables. Set cruise control to avoid speeding in open terrain.

• Best scenic rest: Bighorn Mountains vista point (mile marker 57 on I-90).
• Caffeine stops: Coffee shops in Buffalo (The Laughing Penguino) and Billings (City Brew Coffee).

Family and Child Suitability

Little Bighorn Battlefield has a visitor center and films – great for school-age kids. Pompeys Pillar offers a boardwalk and interactive exhibits. The ride itself is long for toddlers, so pack tablets and snacks.

• Playgrounds: Buffalo City Park, Billings' Pioneer Park.
• Museums: Western Heritage Center in Billings has hands-on activities.

Hidden Off-Route Spots

Consider the ghost town of Kirwin (near Meeteetse, WY) – requires high-clearance vehicle. Or Hot Springs State Park in Thermopolis, WY (90-min detour south).

The first highlight is the Bighorn National Forest, with options for short hikes. At Powder River Pass (elevation 9,666 ft), pull over for panoramic views. West of Buffalo, the terrain flattens into ranching country.
