Montana Highway 1

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, through Anaconda and Philipsburg, to Drummond. Both the beginning and endpoints of the road are on Interstate 90. It is known as the Pintler Veterans' Memorial Scenic Highway, or, informally, the Pintler Scenic Loop. It also provides access to 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.
