Route description
Highway 57 serves as a north–south route in southeast Minnesota between Kasson, Mantorville, Wanamingo, and Hader.

Highway 57 is a two-lane undivided highway its entire length, except for a small portion in the city of Kasson. The route begins in Kasson, and heads through the center of town. Two miles north of Kasson, the route enters historic Mantorville and goes by some landmarks, such as the Hubbell House. North of Mantorville, Highway 57 is very lightly traveled and doesn't enter another incorporated city for twenty miles (32 km). The route intersects State Highway 60 at Wanamingo. Highway 57 then heads north four more miles to its northern terminus at its intersection with U.S. Highway 52 in Hader.

Highway 57 is also known as Mantorville Avenue in the city of Kasson. The route is also known as Main Street in the cities of Mantorville and Wanamingo.

History
Highway 57 was first commissioned as Minnesota Constitutional Route 57 in 1920. Constitutional Route 57 only extended from Highway 14 in Kasson to Mantorville. The remainder of the route north to Hader was authorized in 1934. Highway 57 was completely paved by 1958. The route was extended south of the original terminus in Kasson in 1980 to meet the U.S. 14 bypass.

Highway 57 was the shortest constitutional route in the 1920 Minnesota highway plan, then only three miles in length between Kasson and Mantorville.
