Route description
SH 172 begins in the south at the New Mexico state line where the road becomes New Mexico State Road 511. From there, the route travels through the Southern Ute Indian Reservation northward through Ignacio where it meets the western end of State Highway 151. From Ignacio, the road gradually arcs to the west and passes westward through Falfa before again turning northward to meet its northern end at a junction with U.S. Highway 160 approximately eight miles southeast of Durango.
History
The route was established in the 1930s, when it connected U.S. Route 160 to Arboles. The route was paved from US 160 to Ignacio by 1954 and to Arboles by 1960. The southern terminus was changed to the New Mexico state line by 1972.[2]
Major intersections
The entire route is located in La Plata County.
