The Mississippi River is the second-longest river and chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,320 miles (3,730 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km2), of which only about one percent is in Canada. The Mississippi ranks as the fourth-longest river and fifteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the turning span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot.
The 10th Avenue Bridge crosses the Mississippi River near downtown Minneapolis, Minnesota and also in proximity to the University of Minnesota. The bridge was formerly called the Cedar Avenue Bridge from days prior to the construction of the I-35W bridge when it connected to Cedar Ave. The bridge connects 10th Avenue Southeast, on the east side of the Mississippi River to 19th Avenue South, on the west side. The bridge is considered the crowning achievement of Minneapolis city engineer Kristoffer Olsen Oustad, who was one of four prominent Norwegian-American men who designed major structures in the region. It was added to the National Register of Historic Places in 1989, and also marks the downstream boundary of the Saint Anthony Falls Historic District. During the days immediately following the I-35W bridge collapse, the 10th Avenue Bridge was closed to traffic, then later reopened; it was one of the most used locations from which to view the wreckage and the recovery efforts.
The Memphis & Arkansas Bridge, also known as the Memphis–Arkansas Bridge or Memphis–Arkansas Memorial Bridge, is a cantilevered through truss bridge carrying Interstate 55 across the Mississippi River between West Memphis, Arkansas and Memphis, Tennessee. Memphians refer to this bridge as the "Old Bridge" to distinguish it from the "New Bridge", or Hernando de Soto Bridge, upstream.
The Robert Street Bridge is a reinforced concrete multiple-arch bridge that spans the Mississippi River in downtown Saint Paul, Minnesota, United States. The bridge is notable for its complex design that was required to accommodate river traffic, the St. Paul Union Pacific Vertical-lift Rail Bridge crossing underneath it at an angle, and roadways on the downtown side of St. Paul. The bridge is also notable for a monumental reinforced concrete rainbow arch. The rainbow arch not only provides 62 feet of headroom above the river, but also provides a strong aesthetic focus. It was built in 1924–1926 by Fegles Construction Company, Ltd. and designed by Toltz, King & Day. The bridge was added to the National Register of Historic Places in 1989. The bridge as well as Robert Street itself are named after Captain Louis Roberts, a notable French Canadian river boat captain, businessman and early settler of Saint Paul, MN.
The Intercity Bridge, more commonly known as the Ford Parkway Bridge, is a reinforced concrete arch bridge that spans the Mississippi River between Minneapolis, Minnesota and St. Paul, Minnesota, United States. It connects 46th Street in Minneapolis with Ford Parkway in Saint Paul. The bridge is historically significant as one of the largest reinforced concrete bridges ever built in Minnesota. It was built in 1925-1927 by James O. Heyworth, Inc. and was designed by Martin Sigvart Grytbak. The Intercity Bridge was listed on the National Register of Historic Places in 1989. It is notable as one of the monumental concrete rib-arch bridges spanning the high river bluffs along the Mississippi River, along with the Franklin Avenue Bridge, the Third Avenue Bridge, the 10th Avenue Bridge, and the Robert Street Bridge.
The Lake Street-Marshall Avenue Bridge is a reinforced concrete arch bridge that spans the Mississippi River between Minneapolis, Minnesota and St. Paul, Minnesota. It is oriented East-West and connects Lake Street in Minneapolis to Marshall Avenue in St. Paul. St. Paul residents often refer to it as the Marshall Avenue Bridge. The bridge was designed by Howard, Needles, Tammen, and Bergendoff.
Northern Pacific Bridge #9 is a deck truss bridge that spans the Mississippi River in Minneapolis, Minnesota, between the Seven Corners area and the University of Minnesota campus. It was built in 1924 and was designed by Frederick W. Cappelen. Railroad use of the bridge ended in 1981, and in 1999 the bridge was opened to bicycles and pedestrians. It replaced the former Northern Pacific "A Line" bridge.
The Anoka–Champlin Mississippi River Bridge, also known as the Ferry Street Bridge, is a 10-span open spandrel concrete deck arch bridge that spans the Mississippi River between Anoka and Champlin, Minnesota, United States.

Omaha Road Bridge Number 15 is a swing bridge that spans the Mississippi River in St. Paul, Minnesota, United States. It was built in 1915 by the Chicago, St. Paul, Minneapolis and Omaha Railway, though it, and the line from St. Paul to Mendota, was jointly owned with the Chicago, Milwaukee and St. Paul Railway. The causeway curves around Pickerel Lake in Lilydale, Minnesota, before crossing into St. Paul.
Richard P. Braun Bridge is a pair of 10-span concrete girder bridges spanning the Mississippi River between Brooklyn Park, Minnesota and Coon Rapids, Minnesota. The eastbound span was built in 1985 to connect Minnesota State Highway 252 with Minnesota State Highway 610 in Coon Rapids. The westbound span was built in 1999 as part of the continued construction of Highway 610 through Brooklyn Park. Richard P. Braun is a former Mn/DOT Commissioner from 1979–1986.
Betty Adkins Bridge is a pair of concrete girder bridges spanning the Mississippi River between Otsego, Minnesota and Elk River, Minnesota. The northbound bridge was built in 2001, replacing a plate girder bridge that was originally built in 1967 as a two-lane bridge for Minnesota State Highway 101 when the highway was rerouted around Elk River. The southbound bridge was built in 1993 when Highway 101 was expanded to four lanes.
DeSoto Bridge was a trussed deck-arch bridge that spanned the Mississippi River in St. Cloud, Minnesota. It was built in 1958 by the Minnesota Department of Transportation. The bridge was painted black, which is typical for railroad bridges but unusual for a highway bridge. The river banks on either side are relatively high, so the bridge required deep trusses which arched over the river.
Veterans Bridge is a steel girder bridge that spans the Mississippi River in St. Cloud, Minnesota, United States. It was built in 1971 and was designed by Howard, Needles, Tammen & Bergendoff.
The St. Cloud Rail Bridge is a pin-connected truss bridge that spans the Mississippi River in St. Cloud, Minnesota, United States. It was built in 1892 by Great Northern Railway and was probably designed by the railroad. Two of the piers are stone, while a third pier is newer and made of concrete. The bridge has an extra set of bracing that hangs about ten feet below the bottom trusses, appearing to hang like a hammock. This was added to increase the capacity of the bridge.
The Sauk Rapids Bridge was a steel spandrel braced arch bridge that spanned the Mississippi River between the cities of St. Cloud and Sauk Rapids in the U.S. state of Minnesota. It was built in 1942 and was designed by the Minnesota Department of Transportation. The bridge consisted of three spans supported by two piers. It crossed the Mississippi River one-half mile (0.8 km) downstream from the rapids of the Sauk River. The river is still rough and fast-flowing at this location.
The Bridge of Hope is a concrete girder bridge that spans the Mississippi River between Sartell, Minnesota and Sauk Rapids, Minnesota.
