Saint Anthony Falls, or the Falls of Saint Anthony, located at the northeastern edge of downtown Minneapolis, Minnesota, is the only natural major waterfall on the Mississippi River. Throughout the mid-to-late 1800s, various dams were built atop the east and west faces of the falls to support the milling industry that spurred the growth of the city of Minneapolis. In 1880, the central face of the falls was reinforced with a sloping timber apron to stop the upstream erosion of the falls. In the 1950s, the apron was rebuilt with concrete, which makes up the most visible portion of the falls today. A series of locks were constructed in the 1950s and 1960s to extend navigation to points upstream.
The Stone Arch Bridge is a former railroad bridge crossing the Mississippi River at Saint Anthony Falls in downtown Minneapolis, Minnesota. It is the only arched bridge made of stone on the entire Mississippi River. It is the second oldest bridge on the river next to Eads Bridge. The bridge was built to connect the railway system to the new Union Depot, which at that time was planned to be built between Hennepin Avenue and Nicollet Avenue. The bridge was completed in 1883, costing $650,000 at the time. 117 Portland Avenue is the general address of the historic complex.
Minneapolis is officially defined by its city council as divided into 83 neighborhoods. The neighborhoods are historically grouped into 11 communities. Informally, there are city areas with colloquial labels. Residents may also group themselves by their city street suffixes: North, Northeast, South, and Southeast.
The Washington Avenue Bridge carries County Road 122 and the METRO Green Line light rail across the Mississippi River in Minneapolis and connects the East Bank and West Bank portions of the University of Minnesota campus. The bridge has two decks, with the lower deck designated for motor vehicle traffic and light rail trains and the upper deck used for pedestrians and bicycles. It is a utilitarian structure with simple architecture, but it has cultural significance because thousands of students, faculty, staff, and visitors walk across it every day.
The Franklin Avenue Bridge, officially the F.W. Cappelen Memorial Bridge, carries Franklin Avenue over the Mississippi River in Minneapolis, Minnesota. It was designed by Frederick William Cappelen, assisted by Kristoffer Olsen Oustad, both of whom were among four important Norwegian-American engineers working in the region at the time. The reinforced-concrete open-spandrel arched structure was completed in 1923. The bridge's overall length is 1054.7 feet, with a central span of 400 feet. It was added to the National Register of Historic Places in 1978 along with several other area bridges as part of a multiple-property submission. At the time of its completion, the bridge's central span was the longest concrete arch in the world.
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 Cedar Avenue Bridge carries Minnesota State Highway 77 across the Minnesota River between the Minneapolis-St. Paul suburbs of Bloomington and Eagan, Minnesota. The two parallel crossings for northbound and southbound lanes are respectively 5,159 feet and 5,185 feet in length. It was built in 1979, superseding an older swing bridge by the same name that was composed of low-lying truss segments. The modern bridge has three lanes in each direction, in addition to a shoulder which is often used by buses to get past traffic slowdowns.
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.
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 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 Dartmouth Bridge is a steel girder bridge that spans the Mississippi River in Minneapolis between the Cedar-Riverside area and the University of Minnesota campus area. It carries I-94/US 12/US 52. It was built in 1964 and was designed by Parsons Brinckerhoff, Quade and Douglas. It is named for its proximity to Dartmouth Avenue SE, just north of the bridge.
The Hastings High Bridge was a continuous steel through truss bridge that spanned the Mississippi River in Hastings, Minnesota, United States. It was designed by Sverdrup and Parcel and was built in 1951 by Graus Construction Company of Hasting for $356,000. It was demolished in late 2013 when the current Hastings Bridge opened. It had been scheduled to be torn down and replaced by MNDot in 2019, but after the I-35W bridge collapse in Minneapolis, it was re-prioritized and construction started in 2010.
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. It was built in 1929 by the Minneapolis Bridge Company, replacing an 1884 bridge at the same site.
The Plymouth Avenue Bridge is a segmental bridge that spans the Mississippi River in Minneapolis. It was built in 1983 and was designed by Van Doren-Hazard-Stallings. The construction of this bridge was unique, for it was the first segmental concrete girder bridge built in Minnesota. This method of design uses a "form traveler" that shapes the concrete as it is built out from the piers. This avoided the use of falsework and avoided impeding river traffic. The concrete is also engineered to be salt-resistant by the use of post-tensioning. Tubes run through the concrete structure carrying strands of cable. With tension on the cables, the structure is designed to be under compression. This prevents cracks and hinders the intrusion of salt water. Since then, other bridges in Minnesota have used this construction method, including the I-35W Saint Anthony Falls Bridge in Minneapolis, the Wabasha Street Bridge in downtown St. Paul, and the Wakota Bridge in South St. Paul.
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. After only 39 years in service, it experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The National Transportation Safety Board (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. Additional weight on the bridge at the time of failure was also cited by the NTSB as a contributing factor.
The Eastman tunnel, also called the Hennepin Island tunnel, was a 2,000-foot-long (610 m) underground passage in Saint Anthony, Minnesota, dug beneath the Mississippi River riverbed between 1868 and 1869 to create a tailrace so water-powered business could be located upstream of Saint Anthony Falls on Nicollet Island. The tunnel ran downstream from Nicollet Island, beneath Hennepin Island, and exited below Saint Anthony Falls.
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 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.
Hennepin County Road 122 (CR 122) or County State-Aid Highway 122 (CSAH 122) is an unsigned county state-aid highway within the city of Minneapolis, Hennepin County, Minnesota, United States, crossing the Mississippi River on the Washington Avenue Bridge.
