Minnesota State Highway 40 (MN 40) is a 72.723-mile-long (117.036 km) state highway in west-central Minnesota, which travels from South Dakota Highway 20 (SD 20) at the South Dakota state line near Marietta and continues east to its eastern terminus at its intersection with County State-Aid Highway 5 (CSAH 5) in Willmar.

## Route description

[edit]

MN 40 serves as an east–west route between Madison and Willmar in west-central Minnesota.

The route is also known as:

* 1st Street in Madison
* Lac qui Parle Avenue in Milan
* 60th Street throughout Chippewa County

MN 40 crosses Lac qui Parle Lake west of Milan.

Lac qui Parle State Park is located seven miles (11 km) south of the junction of MN 40 and US Highway 59 (US 59) at Milan. The park entrance is located on CSAH 13 near US 59 at Watson.[1]

MN 40 parallels US 12 and US 212 throughout its route in west-central Minnesota.

## 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 c. 1950.[citation needed]

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.[citation needed]

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