Montana Highway 72 (MT 72) in the U.S. state of Montana is a route running northerly from the Wyoming state line to an intersection with U.S. Route 310 (US 310) about one mile (1.6 km) south of the town of Bridger, a distance of approximately 21miles. At the state line, the road becomes Wyoming Highway 120, which continues 38miles to the town of Cody.
Before receiving its current designation, the portion of Highway 72 north of Belfry was a part of Montana Secondary Highway 308 (S-308), and the segment between Belfry and the Wyoming state line was designated as S-397.[2] [3]
