Monticello to Butte Road Trip Guide: Epic Utah-Montana Drive

This 650-mile journey from Monticello, Utah, to Butte, Montana, spans three states and traverses the rugged spine of the American West. The route primarily follows US-191 north through Moab and Price, then merges onto I-15 near Provo, climbing through Salt Lake City and continuing north past the Great Salt Lake. At I-15's junction with I-84 near Tremonton, you'll continue north into Idaho and Montana. The final leg from Dillon to Butte is a 70-mile stretch on I-15, crossing the Continental Divide at Deer Lodge Pass (elevation 5,300 feet). A quirky local fact: The stretch of US-191 between Monticello and Moab is known as the "Moki Dugway" alternative, but the actual Moki Dugway is a steep gravel road off UT-261 near Mexican Hat. This guide covers the paved, efficient route.
