High Quality Content by WIKIPEDIA articles! Minnesota State Highway 371 (MN 371) is a highway in central and north-central Minnesota. The route connects Minnesota`s northern lakes region with the central part of the state. It runs north–south from U.S. Highway 10 (US 10) in Little Falls to US 2 in Cass Lake. MN 371 has become a heavily-traveled arterial route that was once a two-lane roadway over almost all of its length, but has been widened to four lanes across most of its southern half. Much of the traffic utilizing the route is Twin Cities-based traffic heading to their cabins on one of the many northern lakes. Highway 371 is 107 miles (172 km) in length.
