Minnesota State Highway 13 Capital and Alliant Energy would be the biggest wind farm in the state of Minnesota. State Highway 13 was authorized in 1920 from Albert Lea to Jordan. In 1934, the segment between New Prague and Jordan was redesignated Highway 21, and Highway 13 moved to the east and extended north through Prior Lake, Savage, and Burnsville; then northeast to its northern terminus in West Saint Paul. From 1934 to 1935, Highway 13 also ran from Albert Lea south to the Iowa state line. In 1935, U.S. Highway 69 was extended north into Minnesota, assuming that 12 mile section of the
Minnesota State Highway 28 upon crossing the state line. MN 28 parallels MN 27 throughout its route until MN 27 enters Wheaton, Minnesota and then follows Mud Lake and Lake Traverse, heading South/Southwest to Browns Valley, Minnesota where it connects with MN 28. The Sam Brown Memorial State Wayside Park is located on MN 28 in Traverse County at Browns Valley. The highway overlaps MN 27 for the last of its route, until its terminus in Little Falls at the former alignment of US 10, which is now a city street. MN 28 is legally defined as Constitutional Route 28 in the Minnesota Statutes.
