State highway in Deer Lodge and Granite counties, Montana, United States

Montana State Highway 1 (MT 1) is a state highway in Deer Lodge and Granite counties in southwestern Montana, United States, extending west and north from the Anaconda I 90 Junction to Drummond. Both the beginning and endpoints of the road are on Interstate 90. It is known as the Pintler Scenic Loop and provides access to the community of Philipsburg and the communities near Georgetown Lake. MT 1 was one of the first roads to be paved in its entirety in Montana and has seen many changes over the years. The Philipsburg Valley and Georgetown Lake are found along this route as it winds its way through Mountain Landscapes, Open Meadows and Scenic Valleys in this part of southwestern Montana and gains significant elevation in certain places. The highway connects to the Interstate again at the end of this scenic loop. Montana Highway 1 was formerly designated as U. S. Highway 10 Alternate (US 10 ALT). It received its current number after US 10 was decommissioned through the area in 1986.

MT 1 was first designated on October 9, 1922, near its present location. By the next year, the National Parks Highway had been rerouted away from this route. The unsigned MT 1 had been rerouted, now with an overall length of approximately 78 mile (126 km). Also by 1925, the portion of MT 1 traveling from its southern terminus to Anaconda had been paved. Also, the section of the highway near the town of Brown traveling to Stone had been graded, while the rest of the route remained unimproved dirt. By at least 1927, MT 1 had been rerouted, with an overall length of approximately 71 mile (114 km), and the portion of the highway traveling from Stone to its northern terminus had been graded. At least two years later, the entire length of the route had been graded. In 1934, the portion of MT 1 that traveled from modern day milepost 24.190 to the Deer Lodge–Granite County border was reconstructed along its current route. By 1937, MT 1 had been concurrently numbered as US 10, and later that year, US 10 was rerouted, and MT 1 was renumbered as US 10 ALT. Also by that time, the route had been rerouted so that the overall length was approximately 70 mile (113 km), and the entire length of the route had at least a graded gravel surface. In 1951, the entire length of MT 1/US 10 ALT was paved, with an overall length of approximately 66 mile (106 km). Also, the portion of MT 1/US 10 ALT traveling from present day mileposts 9.426 to 9.940 was reconstructed along its current route. Two years later, the portion traveling from modern milepost 62.323 to the northern terminus were reconstructed. In 1975, the portion traveling from Elm Street to Sycamore Street (U 201) was reconstructed to the modern route.
