U.S. 14 enters the state from South Dakota west of Lake Benton. It goes east through several small towns such as Balaton, Tracy, Revere, Lamberton, Sanborn and Sleepy Eye, on a two-lane road until New Ulm, where it is briefly a divided highway. From New Ulm to Mankato, the highway lies north of the Minnesota River. Shortly before coming to the Mankato/North Mankato area, U.S. 14 becomes a freeway bypass, which becomes an expressway east of Mankato. This section is part of the Laura Ingalls Wilder Historic Highway as it passes through Walnut Grove. It currently continues east south of Waseca and at Owatonna, it crosses Interstate 35. It then heads east towards Rochester, with an expressway segment beginning at Minnesota State Highway 56 and continuing east into Rochester. Once it enters Rochester, it has a concurrency with U.S. Route 52. After the concurrency, it continues through Rochester as a divided highway. After Rochester, the highway parallels Interstate 90 until Winona, where U.S. 14 gets picked up by U.S. Route 61. The two highways run concurrently the rest of the way in Minnesota, and cross the Mississippi River at La Crescent over the La Crosse West Channel Bridge.
