Main Channel Bridge (Winona) consists of a pair of bridges, the original cantilever bridge, and a concrete box girder bridge completed in 2016, that span the main channel of the Mississippi River in the United States between Winona, Minnesota, and Latsch Island. Another bridge, the North Channel Bridge, connects the island to rural Buffalo County, Wisconsin. The bridge carries Minnesota State Highway 43, which continues as Wisconsin Highway 54 at the Minnesota/Wisconsin state line on the nearby North Channel Bridge; in Winona, it connects to Winona Street.
Construction on the original cantilever bridge was started just before the U.S. entered World War II, and the construction was hastened to finish in November 1942, despite labor shortages, difficulty obtaining materials, and high water. It was built in 1941–1942 by the Minnesota Department of Transportation (MnDOT).
On May 17, 2008, the United States Postal Service announced that the bridge would be on the Minnesota sesquicentennial commemorative stamp. [1]
Following an inspection of the bridge's gusset plates, the Minnesota Department of Transportation closed the bridge on June 3, 2008, with over 60-mile-long (97 km) detours as an alternative. [2] The bridge reopened on June 14, 2008.
After considering a number of alternatives, including rehabilitation of only the original bridge, or construction of a new bridge and demolition of the original bridge, on August 23, 2012, the Minnesota Department of Transportation announced approval for plans to build a new two-lane concrete box girder bridge, prior to rehabilitating the original bridge. [3] Construction of the new bridge began immediately upstream of the cantilever bridge in July 2014, and opened for traffic in August 2016. Following the opening of the new bridge, the original cantilever bridge closed for rehabilitation. [4] The rehabilitated cantilever bridge opened July 1, 2019, allowing 2 lanes in each direction.

The Third Avenue Bridge is a landmark structure of the city of Minneapolis, Minnesota, United States, originally known as the St. Anthony Falls Bridge. It carries road traffic across the Mississippi River and upper fringes of Saint Anthony Falls. The multi-arched bridge meets with Third Avenue in downtown Minneapolis at its south end, but curves as it crosses the river, and connects with Central Avenue on its north end. The shallow "S" curve in the bridge was built to avoid fractures in the limestone bedrock that supports the bridge piers. The road is also designated Minnesota State Highway 65. Construction began in 1914, and it opened four years later in 1918. The bridge, which uses Melan arches of an open spandrel design, has been modified since that time. The 2,223-foot crossing was designed by city engineer Frederick W. Cappelen, who also created plans for other similar bridges in Minneapolis such as the Franklin Avenue Bridge. It cost US$862,254.00 at the time of construction.
The 10th Avenue Bridge crosses the Mississippi River near downtown Minneapolis, Minnesota and also in proximity to the University of Minnesota. The bridge historically was 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 Seven Corners area of the Cedar-Riverside, Minneapolis neighborhood is at the south end of the bridge. The downstream end of the lower Saint Anthony Falls lock and dam extends under the bridge. The historic Southeast Steam Plant is also nearby.
The Black Hawk Bridge spans the Mississippi River, joining the town of Lansing, in Allamakee County, Iowa, to rural Crawford County, Wisconsin. It is the northernmost Mississippi River bridge in Iowa.
The Stillwater Bridge is a vertical-lift bridge crossing the St. Croix River between Stillwater, Minnesota, and Houlton, Wisconsin. It formerly connected Minnesota State Highway 36 and Wisconsin Highway 64. Around 18,000 vehicles crossed the bridge daily. The new St. Croix Crossing bridge crossing the St. Croix river valley to the south of Stillwater replaced its purpose, having opened to highway traffic on August 2, 2017, leaving the Stillwater Lift Bridge to be preserved and to be converted to bicycle/pedestrian use.
The North Channel Bridge crosses the north channel of the Mississippi River between Latsch Island and Buffalo County, Wisconsin.
The Smith Avenue High Bridge or the High Bridge is an inverted arch bridge that carries Minnesota State Highway 149 and Smith Avenue over the Mississippi River in Saint Paul, Minnesota, United States. It was built and opened in 1987 at a cost of $20 million. The bridge carries two lanes of street traffic over the river and is the highest bridge in St. Paul, with a deck height of 160 ft (49 m) and a clearance below of 149 ft (45 m).
The I-90 Mississippi River Bridge, or the Dresbach Bridge, consists of a pair of parallel bridges that traverse the Mississippi River, connecting the La Crosse, Wisconsin area to Dresbach in rural Winona County, Minnesota. The current bridge was fully opened to traffic in October 2016, replacing a previous 1967 plate girder bridge. It is part of the Interstate 90 route. There is another automobile crossing a few miles south of this bridge; the Mississippi River Bridge, a combination of two bridges, and the La Crosse West Channel Bridge, connecting La Crescent, Minnesota and La Crosse, Wisconsin.
Minnesota State Highway 280 is a 3.710-mile-long (5.971 km) highway in the Twin Cities region of Minnesota that travels from its Interchange with Interstate 94/U.S.Route 12/US Route 52 (I-94/US 12/US 52) in Saint Paul to its interchange with I-35W in Roseville.
The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967 and was Minnesota's third busiest, carrying 140,000 vehicles daily. It experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The NTSB cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets, and that additional weight on the bridge at the time contributed to the catastrophic failure.
Minnesota State Highway 26 is a state highway in southeastern corner of the U.S. state of Minnesota. At 21 miles (34 km) in length, Highway 26 runs parallel to the Mississippi River and is a portion of the Great River Road. The route begins at the Iowa state line where it continues as Iowa Highway 26, and ends at an intersection with Minnesota State Highway 16 south of La Crescent.
Minnesota State Highway 43 is a highway in southeast Minnesota, which runs from its intersection with State Highway 44 in Mabel and continues north to its northern terminus at the Wisconsin state line at Winona, where it becomes Wisconsin Highway 54 upon crossing the Mississippi River.
Lock and Dam No. 7 is a lock and dam located on the Upper Mississippi River at river mile 702.5 near the cities of La Crescent, Minnesota and Onalaska, Wisconsin. It forms pool 7 and Lake Onalaska. The facility was constructed in the mid-1930s and placed in operation on April, 1937. It underwent major rehabilitation from 1989 through 2002. The lock and dam are owned and operated by the St. Paul District of the United States Army Corps of Engineers-Mississippi Valley Division.
Trunk Highway 243 and State Trunk Highway 243 are two short state highways in the U.S. states of Minnesota and Wisconsin. They connect MN 95 in Franconia Township, Minnesota with WIS 35 in Osceola, Wisconsin. The two highways meet at the state line on a bridge across St. Croix River. The combined highway is 1.53 miles (2.46 km) in length, 1.23 miles (1.98 km) in Minnesota and 0.30 miles (0.48 km) in Wisconsin. The two highways were designated in 1949. The bridge across the St. Croix River dates to 1953.
The Washington Bridge was a cantilever truss bridge over the Missouri River at Washington, Missouri over which Route 47 passed between Franklin County, Missouri and Warren County, Missouri. It has also been known as the Route 47 Missouri River Bridge.
The I-35W Saint Anthony Falls Bridge crosses the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota in the U.S., carrying north–south traffic on Interstate Highway 35W. The ten-lane bridge replaced the I-35W Mississippi River bridge, which collapsed on August 1, 2007. It was planned and is maintained by the Minnesota Department of Transportation (MnDOT). The planning, design, and construction processes were completed more quickly than normal because Interstate 35W is a critical artery for commuters and truck freight. The bridge opened September 18, 2008, well ahead of the original goal of December 24.
Kern Bridge or Yaeger Bridge crossed the Le Sueur River in Blue Earth County in the U.S. state of Minnesota. It was built in 1873 using a bowstring through truss design by the Wrought Iron Bridge Company. It was 183.5 feet (56 m) long and carried a local road. It was listed on the National Register of Historic Places in 1980 as Minnesota's only bowstring arch truss bridge and oldest road bridge still in use. However, it was closed to vehicle traffic in 1991.

The Winona Rail Bridge was a swing bridge that spanned the Mississippi River between Winona, Minnesota, and Winona Junction in Buffalo, Buffalo County, Wisconsin. It was built to link the Winona and St. Peter Railroad with the La Crosse, Trempealeau & Prescott Railroad. Both became part of the Chicago and North Western Transportation Company (C&NW). The swing span was removed, but the box girder portion of the bridge still extends from Latsch Island just downstream of the current Main Channel Bridge. Piers from the original 1871 bridge and the box girders are in the North Channel just downstream of the current North Channel Bridge.
