Montana Highway 5 is a highway connecting with North Dakota's Highway 5, the 337 mile long ND highway. Montana 5 runs from the ND border to Scobey, Montana. It was formed in 1939, with its beautiful scenery along the way it makes it one of the best roads. However, the road closely follows the topographic contours of the land and, in the extreme winter climate of northeastern Montana, this often leads to road closures due to drifting snow.
