Montana Highway 40


Montana Highway 40 is a short, state highway in Flathead County, Montana. It connects U.S. Route 93 south of Whitefish to US 2 west of Columbia Falls.

Route description

MT 40 begins at US 93 on the southern outskirts of Whitefish and proceeds eastward in a roughly straight line to its terminus with US 2 west of Columbia Falls.
MT 40 forms the central part of the most-direct link between the two cities, allowing travel from the Hi-Line communities and Glacier National Park to the communities of the Columbia Valley in British Columbia without needing to detour south via Kalispell or north via the Crowsnest Pass between British Columbia and Alberta.

History

The basic route of MT 40 has been in place since the 1930s, and is seen on the 1935 state map. For a brief time in the 1940s, it was even signed as MT 37, overlaid on US 93 to north of Eureka and then going to Libby, as seen on the 1942 map.
The MT 40 designation is clearly visible on the 1949 state map. MT 40 extended through Columbia Falls to the current US 2/Secondary Highway 206 junction until the US 2 and S-206 routings were swapped in 1983.
MT 40 is a rare example in the state road log of a national highway system route that is fully federally funded, yet is signed as a state highway, and not as a U.S. Route or Interstate.
