Route description

Highway 139 serves as a north–south route between the Iowa state line and the city of Harmony. It is also known as Main Avenue in Harmony.

The route passes near Niagara Cave.

The route is legally defined as Route 79 in the Minnesota Statutes.^[2] It is not marked with this number.

History

Highway 139 was authorized in 1933.^[1]

The route was paved by 1953.^[3]

Highway 139 was numbered to match adjoining Iowa Highway 139. This is the only example where Minnesota numbered a route to match an existing route in Iowa, rather than the opposite. Iowa renumbered its state highways that crossed into Minnesota in the early 1960s to match the Minnesota numbers.^[3]

Major intersections

The entire route is in Fillmore County.
