Minnesota State Highway 7, or Trunk Highway 7, (MN 7, TH 7) is a state highway in Minnesota, which runs from its intersection with MN 28 near Beardsley and continues east to its terminus with MN 100 and County Road 25 (CR 25) in St. Louis Park. The highway runs east–west for approximately through mostly rural farmland in the central part of the state. On its western end, it is part of the Minnesota River Valley Scenic Byway where it runs northwest–southeast along the Minnesota River and associated lakes near the border with the adjoining state of South Dakota. For roughly of its route, it runs concurrently with U.S. Highway 59 (US 59) between Appleton and Montevideo. In Montevideo, the highway turns to the east cutting across the state. It passes through several small towns before entering the Twin Cities metropolitan area. In the metro area, MN 7 follows an expressway through several suburbs before terminating in St. Louis Park. Two different segments have been listed on the National Highway System, system of roads considered important to the country.
The highway was first designated along a series of roads between Appleton and Minneapolis around 1933. At first these roads were a mixture of gravel and bitumen surfaces, the latter a forerunner of today's asphalt. Within the first year or so, the western end was extended to terminate MN 7 in the Ortonville area. In 1958, the highway was extended to its modern western terminus at Beardsley by replacing another trunk highway. The section that is now an expressway in the Twin Cities was expanded by the 1950s, and the whole highway was paved in a hard-surface by the end of that decade. The highway was truncated in the Twin Cities to its current eastern terminus in the 1980s. The scenic byways designations were applied at the state and federal levels in 1995 and 2002, respectively.
Route description
Legally, MN 7 is defined as several different constitutional and legislative routes in state law. The highway follows roadways defined as parts of constitutional routes 12 and 40 in Minnesota Statutes § 161.114. The remainder of the highway follows all, or part, of legislative routes 119, 147, 148, 304, and 319 in the Minnesota Statutes § 161.115. The highway is not marked with these routes number along the actual highway. The route of MN 7 between Ortonville and Montevideo along with the segment between I-494 and MN 100 in the Twin Cities have been listed on the National Highway System, a system of roads important to the nation's economy, defense, and mobility. Like other trunk highways in the state, MN 7 is maintained by the Minnesota Department of Transportation (MnDOT). According to the department, up 12,000 vehicles a day used the highway outside of the Twin Cities, and up to 55,000 vehicles traveled the highway daily in the metro area in 2010.
Beardsley to Montevideo
The highway starts at an intersection with MN 28 on the eastern edge of Beardsley and heads south. From here, MN 7 passes through farm fields before turning southeasterly along the shore of Big Stone Lake. The lake is the source of the Minnesota River and forms the Minnesota–South Dakota state line in Big Stone County. The road turns eastward along a bend in the lake near the community of Foster before running further inland around Big Stone Lake State Park. Past the park, MN 7 curves to the south along the shore and continues to Ortonville. The highway follows 2nd Street through town along the lake shore and through residential neighborhoods. South of the end of the lake, MN 7 merges with US 12, and the two highways run concurrently for about a couple blocks. South of town, MN 7 merges onto US 75 and the combined highway runs along the Minnesota River. The roadway also runs parallel to a line of the BNSF Railway used by the Twin Cities and Western Railroad in the area. East of the Big Stone National Wildlife Refuge and the town of Odessa, US 75 and the scenic byway turn south to cross the river, separating from MN 7 which continues along the northern banks of the river.
The western edge of St. Louis Park is marked by the interchange with US 169. The area immediately adjacent to MN 7 in this suburb is filled with commercial properties on either side of access roads. East of Texas Ave S, MN 7 becomes a freeway with three interchanges. The first is a dumbbell interchange with Louisiana Ave. East of Louisiana Avenue, the highway is parallel to a line of the Twin Cities and Western Railroad. There is another interchange for Wooddale Avenue before MN 7 meets, and terminates at, the interchange for MN 100 The expressway continues east for approximately another mile (1.6 km) as CR 25. At the time, the highway was under construction between Ortonville and Appleton. From its junction with MN 119, MN 7 was a gravel road southeasterly to Montevideo before turn east on a bituminous surface to Clara City. From there east to the Waconia area, the highway was gravel, and the remainder was bituminous. No sections at the time were paved in asphalt. By 1952, the highway had been expanded to four lanes between Excelsior and the Twin Cities. In 1958, the highway was extended northwesterly along US 75 from Odessa to Ortonville and continuing on to Beardsley. The highway between Beardsley and Ortonville had been MN 103 since the 1930s. From 1965 to either 1987 or 1988, the eastern terminus was located at the intersection of Lake Street and France Avenue in Minneapolis; the part, about long, between the interchange with MN 100 and the intersection of Lake Street and France Avenue is now called County State-Aid Highway 25. In 1995, the section between MN 28 and the southern US 75 junction was named a Minnesota State Scenic Byway; it was also made a National Scenic Byway on June 13, 2002.
