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 swing 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 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.
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily becauses it uses materials efficiently.
The Hennepin Avenue Bridge is the structure that carries Hennepin County State Aid Highway 52, Hennepin Avenue, across the Mississippi River in Minneapolis, Minnesota, at Nicollet Island. Officially, it is the Father Louis Hennepin Bridge, in honor of the 17th-century explorer Louis Hennepin, who was the first European to see the Saint Anthony Falls, a short distance downriver. Two of the three previous structures have been suspension bridges, while a third—which existed nearly a century—was composed of steel arch spans. The original crossing, which opened as a toll bridge on January 23, 1855, is believed to have been the first permanent span across the Mississippi at any point. Other bridges were completed in 1876, 1891, and most recently 1990. Today, the bridge's main span is 190 metres (620 ft) in length.

Nicollet Island is an island in the Mississippi River just north of Saint Anthony Falls in central Minneapolis, Minnesota. According to the United States Census Bureau the island has a land area of 194,407 square metres (0.075 sq mi) and a 2000 census population of 144 persons. The island makes up a large part of the city-designated Nicollet Island/East Bank neighborhood. The island is named for cartographer Joseph Nicollet, who mapped the Upper Mississippi in the 1830s.
The Huey P. Long Bridge, located in Jefferson Parish, Louisiana, is a cantilevered steel through-truss bridge that carries a two-track railroad line over the Mississippi River at mile 106.1, with three lanes of US 90 on each side of the central tracks. It is several kilometers upriver from the city of New Orleans. The East Bank entrance is at Elmwood, Louisiana, and the West Bank at Bridge City.
Saint Anthony Main refers to an area of buildings with multiple owners located on Main Street across from Saint Anthony Falls in the Nicollet Island/East Bank, Minneapolis section of Southeast, Minneapolis in the U.S. state of Minnesota.

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).

Minneapolis BNSF Rail Bridge is a combination plate girder bridge and truss bridge that spans the main channel of the Mississippi River between downtown Minneapolis, Minnesota and Nicollet Island in Minneapolis. It is located adjacent to the current Federal Reserve Bank of Minneapolis.
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.
Broadway Avenue Bridge is a girder bridge that spans the Mississippi River in Minneapolis, Minnesota. Designed by Norman C. Davis and Shawn Pierson Bruns of Van Doren-Hazard-Stallings, it was built in 1987. The bridge has a rather streamlined shape, but its piers are more ornate. The piers have two flat columns that taper together, with a base that extends out to the full width of the bridge.

The Minneapolis Streetcar System was a proposed streetcar system for the city of Minneapolis, Minnesota. Extensive studies and plans for the new system were completed in 2007 and presented to the Minneapolis City Council in January 2008; on April 2, 2010, the Council voted to approve the plans and seek funding. On December 21, 2010 the Federal Transit Administration granted $900,000 to further study the Nicollet and Central Avenue corridors. In June 2021, after no further development on the system, a bill authorized the Metropolitan Council to use funds collected for the Nicollet-Central line to be spent on bus rapid transit funding.

The district's archaeological record is considered to be one of the most-endangered historic sites in Minnesota.
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 King Iron Bridge & Manufacturing Company was a late-19th-century bridge building company located in Cleveland, Ohio. It was founded by Zenas King (1818–1892) in 1858 and subsequently managed by his sons, James A. King and Harry W. King and then his grandson, Norman C. King, until the mid-1920s. Many of the bridges built by the company were used during America's expansion west in the late 19th century and early 20th century, and some of these bridges are still standing today.
Arch Street Bridge is Parker truss bridge over the Passaic River in Paterson, New Jersey. It was built in 1907 and rehabilitated in 1997.
