Jamestown ND to Pinedale WY Road Trip Guide – Best Stops

This 650-mile drive from Jamestown, ND (the 'Buffalo City') to Pinedale, WY (gateway to the Wind River Range) traverses three states and a dramatic shift in ecology. The route follows I-94 W and US-83 S from Jamestown to Bismarck, then I-94 W to I-94/US-85 W near Dickinson, and finally US-85 S and WY-28 W into Pinedale. Expect roughly 10-11 hours of driving time, not counting stops.

Along the way, you cross the Missouri River at Bismarck, a historical boundary of the Lewis and Clark expedition. One local quirk: the speed limit drops to 65 mph in North Dakota construction zones, but enforcement is strict, so watch your speed.

Infrastructure Safety and Road Quality

The Interstate (I-94) is well-maintained with rumble strips and wide shoulders. US-83 south of Bismarck is a two-lane undivided highway; pass with caution. US-85 W from Dickinson to WY-28 is mostly straight but has cattle guards and occasional gravel cross streets.

Cell coverage drops between Bowman and Gillette (50 miles of no signal). Wyoming Highway 28 from Lander to Pinedale is a winding two-lane with steep grades; watch for logging trucks.

Natural Landscapes and Attractions

• Theodore Roosevelt National Park (South Unit) is a 30-minute detour off I-94 near Medora, ND. See wild horses and bison.
