U.S. Highway 12 (US 12) is a 192.798-mile-long (310.278 km) U.S. Highway in west-central and east-central Minnesota, which travels from the South Dakota state line at Ortonville near Big Stone Lake and continues east to the St. Croix River at the Wisconsin state line. US 12 connects the cities of Ortonville, Benson, Willmar, Litchfield, Minneapolis, and Saint Paul.
From the South Dakota state line at Ortonville, to Orono in the Twin Cities area, US 12 is mostly a rural two-lane highway with a 60-mile-per-hour (97 km/h) posted speed limit, with slower speed limits through towns and a four-lane surface arterial segment through the city of Willmar. From Orono to Wayzata, US 12 is a two-lane freeway/super-2 bypass around Long Lake. From western Wayzata to Interstate 394 (I-394) in Minnetonka, US 12 is a six-lane freeway, with a posted speed limit of 65 miles per hour (105 km/h). East of I-494, US 12 is invisibly concurrent with I-394 and I-94 through Minneapolis and Saint Paul to the Wisconsin state line at Hudson.
Legally, the Minnesota section of US 12 is defined as unmarked Constitutional / Legislative Routes 149, 26, and 10 in Minnesota Statutes §§ 161.115(80) and 161.114(2). US 12 is not marked with these legislative numbers along the actual highway.
US 12 was established on November 11, 1926. In 1929, the only sections paved were between Litchfield and Willmar; and between Wayzata through the Twin Cities to Wisconsin. The entire route was paved by 1940.
