History[edit]

Most of MN 40 was authorized in 1933.

The section of the route between US 75 at Madison and the South Dakota state line was authorized circa 1950.[1]

MN 40 was still gravel in 1940. The route was mostly paved by 1953, except for just west of Willmar. MN 40 was completely paved by 1958.[1]

In 2009, its eastern terminus was moved from US 12 in Willmar to CR 5 (30th Street SW).[1]
