The Steel Bridge is a through truss, double-deck vertical-lift bridge across the Willamette River in Portland, Oregon, United States, opened in 1912. Its lower deck carries railroad and bicycle/pedestrian traffic, while the upper deck carries road traffic, and light rail (MAX), making the bridge one of the most multimodal in the world. It is the only double-deck bridge with independent lifts in the world and the second oldest vertical-lift bridge in North America, after the nearby Hawthorne Bridge. The bridge links the Rose Quarter and Lloyd District in the east to Old Town Chinatown neighborhood in the west.

The Fort Madison Toll Bridge is a tolled, double-decked swinging truss bridge over the Mississippi River that connects Fort Madison, Iowa, and unincorporated Niota, Illinois. A double-track railway occupies the lower deck of the bridge, while two lanes of road traffic are carried on the upper deck. The bridge is about 1 mile (1.6 km) long with a swing span of 525 feet (160 m), and was the longest and largest double-deck swing-span bridge in the world when constructed in 1927. It replaced an inadequate combination roadway/single-track bridge completed in 1887. The main river crossing consists of four 270-foot (82 m) Baltimore through truss spans and a swing span made of two equal arms, 266 feet (81 m) long. In 1999, it was listed in the National Register of Historic Places under the title, Fort Madison Bridge, ID number 99001035. It was also documented as survey number IA-62 by the Historic American Engineering Record, archived at the Library of Congress. Construction and photographic details were recorded at the time in Scientific American magazine.
The Memphis & Arkansas Bridge, also known as the Memphis–Arkansas Bridge or inaccurately as the Memphis–Arkansas Memorial Bridge, is a cantilevered through truss bridge carrying Interstate 55 across the Mississippi River between West Memphis, Arkansas and Memphis, Tennessee.

The Harahan Bridge is a cantilevered through truss bridge that carries two rail lines and a pedestrian bridge across the Mississippi River between West Memphis, Arkansas, and Memphis, Tennessee. The bridge is owned and operated by Union Pacific Railroad and is the second longest pedestrian/bicycle bridge in the United States. It was built with roadways cantilevered off the sides of the main structure for vehicles. These roadways are owned by the cities of Memphis, Tennessee, and Crittenden County, Arkansas, and were used from 1917–1949, until the Memphis & Arkansas Bridge opened 400 feet (120 m) south of the Harahan. The bridge was named in honor of railroad executive James Theodore Harahan, former president of the Illinois Central Railroad, who was killed in a railroad accident during the construction of the bridge. In February 2011, Union Pacific Railroad officials agreed to the idea of converting the 1917 roadways into a bicycle-pedestrian walkway across the river. In June 2012, Memphis was awarded a $14.9 million federal grant to build the walkway. The overall project was expected to cost $30 million, of which about $11 million was used for the Harahan Bridge portion. Construction was completed in 2016.
The Beaver Bridge is a rail bridge spanning the Ohio River between Monaca and Beaver, Pennsylvania. It consists of two spans: a southern cantilever through truss of 769 feet (234 m) with 320-foot (98 m) anchor arms; and a northern camelback through truss of 370 feet (110 m). The bridge currently carries two tracks of CSX Transportation.
The Burlington Bridge is a vertical-lift railroad bridge across the Mississippi River between Burlington, Iowa, and Gulfport, Illinois, United States. It is currently owned by BNSF Railway and carries two tracks which are part of BNSF's Chicago–Denver main line.
George Shattuck Morison was an American engineer. A classics major at Harvard who trained to be a lawyer, he instead instead became a civil engineer and leading bridge designer in North America during the late 19th century. During his lifetime, bridge design evolved from using 'empirical “rules of thumb” to the use of mathematical analysis techniques'. Some of Morison's projects included several large Missouri River bridges as well as the great cantilever railroad bridge at Memphis, Tennessee, and the Boone, Iowa viaduct. Morison served as president of the American Society of Civil Engineers (1895) as well as a member of the British Institute of Civil Engineers winning that institution's Telford Medal in 1892 for his work on the Memphis bridge. In 1899, he was appointed to the Isthmian Canal Commission and recommended it be built at Panama.
The Tower Bridge is a vertical lift bridge across the Sacramento River, linking West Sacramento in Yolo County to the west, with the capital of California, Sacramento, in Sacramento County to the east. It has also been known as M Street Bridge. It was previously a part of U.S. Route 40 until that highway was truncated to east of Salt Lake City as well as US Route 99W, which served the western portion of the Sacramento Valley from Sacramento to Red Bluff. The bridge is maintained by the California Department of Transportation as part of State Route 275 and connects West Capitol Avenue and Tower Bridge Gateway in West Sacramento with the Capitol Mall in Sacramento.

The bridge has three Pratt deck trusses, each 112 feet (34 m) in length, and three Parker pony trusses, also 112 feet (34 m) long, with the balance of the bridge length in steel girder truss spans. The bridge is 24 feet (7.3 m) wide.
The North Fork Bridge carries Arkansas Highway 5 over the North Fork River, or the North Fork of the White River, in Norfork, Arkansas, United States.

The Judsonia Bridge is a historic bridge, carrying Van Buren Street across the Little Red River on the south side of Judsonia, Arkansas. It is a three-span metal truss swing bridge, with a total structure length of 397 feet (121 m). Its center span is 266 feet (81 m) long, and is mounted on a pivot on a central pier. It and the two approach trusses are all Warren trusses. Built in 1924, it is one of three known swing bridges in the state, and the only one with a cantilevered swinging truss. It was closed to traffic in 2007, and reopened in 2013 after restoration.
