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. This highway was originally part of Montana 37 until around 1942. That previous incarnation of 37 ran from Libby through
