Montana Highway 2 (MT 2) is a 64.65-mile-long (104.04 km) state highway in the southern part of the U.S. state of Montana. It extends from Interstate 15 Business (I-15 BL) and I-90 BL in Butte to Interstate 90 in Three Forks. Previously, this roadway was a part of U.S. Route 10 (US 10). Sections of MT 2 are unsigned.
Route description
MT 2 begins in downtown Butte at the intersection of Park Street and Montana Street,[1] and travels concurrently with 1-15 BL and I-90 BL to an interchange with I-15 and I-90, which also travels concurrently through the city. The highway heads south and then southeast through rural Silver Bow County. The highway crosses Pipestone Pass and enters Jefferson County. It travels through Whitehall and Cardwell. As it nears Three Forks, MT 2 meets US 287 and the two highways travel concurrently for approximately ten miles (16 km). Just west of Three Forks, MT 2 splits away from US 287 and then enters the city. The highway ends at another interchange with I-90; the roadway continues as Secondary Highway 205 (S-205).
