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 1800’s, 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.

The Twin Cities Assembly Plant is a former Ford Motor Company manufacturing facility in Saint Paul, Minnesota, United States, that operated from 1925 to 2011. In 1912, Ford's first assembly and sales activities in Minnesota began in a former warehouse in Minneapolis. By 1925, Ford had relocated its local operations to the bluffs above the Mississippi River in the Highland Park neighborhood of Saint Paul. In 2006, Ford officials announced plans to close the factory, though it operated for three years past the 2008 closure date initially announced. At the time of its closure, it was the oldest Ford plant in continuous operation. The plant's final truck was completed on December 16, 2011. All of the facility's buildings were demolished and the site underwent extensive environmental remediation in the late 2010s, paid for by the Ford company. Following a multi-year planning and community engagement process, the site was sold to the Ryan Companies, who began redevelopment of the site in 2020 as Highland Bridge, a 122-acre residential and commercial district.
The Mississippi National River and Recreation Area is a 72-mile (116 km) and 54,000-acre (22,000 ha) protected corridor along the Mississippi River through the Minneapolis–Saint Paul metro in the U.S. state of Minnesota, from the cities of Dayton and Ramsey, to just downstream of Hastings. This stretch of the upper Mississippi River includes natural, historical, recreational, cultural, scenic, scientific, and economic resources of national significance. This area is the only national park site dedicated exclusively to the Mississippi River. The Mississippi National River and Recreation Area is sometimes abbreviated as MNRRA or MISS, the four letter code assigned to the area by the National Park Service. The Mississippi National River and Recreation Area is classified as one of four national rivers in the United States, and despite its name it is technically not one of the 40 national recreation areas.
Ford Dam, officially known as Lock and Dam No. 1, is on the Upper Mississippi River and is located between Minneapolis and Saint Paul, Minnesota just north of the confluence of the Mississippi with the Minnesota River at Mississippi River mile 847.9, in Minneapolis. The powerhouse portion was previously owned by the Ford Motor Company, which operated a hydroelectric power station to feed electricity to its Twin Cities Assembly Plant on the east side of the river. It was sold to Brookfield Power Co. in April 2008. The dual-lock facility and dam was built and is operated by the St. Paul district of the U.S. Army Corps of Engineers' Mississippi Valley Division.
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.

Fort Patrick Henry Dam is a hydroelectric dam on the South Fork Holston River within the city of Kingsport, in Sullivan County in the U.S. state of Tennessee. It is the lowermost of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the early 1950s to take advantage of the hydroelectric potential created by the regulation of river flow with the completion of Watauga Dam, South Holston Dam, and Boone Dam further upstream in preceding years. The dam impounds the 872-acre (353 ha) Fort Patrick Henry Lake. While originally built for hydroelectric generation, the dam now plays an important role in the regulation of water flow and water temperature for the John Sevier Fossil Plant and other industrial plants downstream. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017.

St. Anthony Falls in Minneapolis, Minnesota, is the only natural falls on the Mississippi River. Since almost the beginning of settlement in the area by European descendants, the St. Anthony Falls have been used for waterpower. The first allowed settlers were at Ft. Snelling, where construction began in 1820. A sawmill was operating 1821 and a flour mill in 1823. As soon as the land at the sides of the falls became available it was purchased with the intent of using the waterpower of the falls. First lumber mills covered the falls, cutting lumber floated down the Mississippi. After 1870 flour mills started to dominate the area. From 1880 to 1930 the area was the number one flour producer in the US. In later years, some of the power came from steam, but in 1923 half of the waterpower used was for flour milling. Other industries have also used the waterpower.
