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.
Mullan Road was the first wagon road to cross the Rocky Mountains to the Inland of the Pacific Northwest. It was built by U.S. Army troops under the command of Lt. John Mullan, between the spring of 1859 and summer 1860. It led from Fort Benton, which at the time was in the Dakota Territory, then Idaho Territory from July 1863, and into Montana Territory beginning in May 1864. The road eventually stretched all the way from Fort Walla Walla, Washington Territory, near the Columbia River to the navigational head of the Missouri River, which at the time was the farthest inland port in the world). The road previewed the route approximately followed by modern-day Interstate 15 and Interstate 90 through present-day Montana, Idaho, and Washington.

The Little Missouri River Bridge, also known as the Nachitoch Bluff Bridge, is a historic bridge between rural southern Clark County, Arkansas and Nevada County, Arkansas. Now closed to traffic, it once carried County Road 179 over the Little Missouri River. Believed to be built in 1910, it is the only known Camelback Pratt truss bridge in the state. Its main span measures 185 feet (56 m), with a secondary Pratt truss span measuring 110 feet (34 m) in length, and there are I-beam-supported approaches on either side, giving the bridge a total length of 315 feet (96 m). The bridge is located on the historic route of the Natchitoches Trace, an early colonial French-Spanish trail through the area.
The Middle Fork of the Little Red River Bridge, also known as the Shirley Railroad Bridge, is a historic bridge in Shirley, Arkansas. It is a single-span iron Baltimore through truss, with a main span 153 feet (47 m) long, and steel beam approach spans giving it a total length of 339 feet (103 m). The main span rests on large concrete piers set in the river. The bridge was built in 1908 for the Missouri and North Arkansas Railroad, and carried the railroad until 1949. In 1978 the tracks were covered by a concrete deck, and the bridge was converted to single-lane vehicular road use, carrying County Road 125.
Eveland Bridge is located southwest of Oskaloosa, Iowa, United States. It carried traffic of Fulton Avenue over the Des Moines River, spanning 647 feet (197 m). After receiving multiple petitions, the Mahaska County Board of Supervisors decided in April 1875 to build a bridge, replacing a ferry service that operated at this point along the river beginning in 1854. They contracted with the Fort Wayne Bridge Works of Fort Wayne, Indiana, to build the new bridge for $25,200. It was designed by C. W. Tracy, a civil engineer. The Whipple through truss span was completed in the summer of 1877. This style was rarely chosen for wagon trusses in Iowa, which means few were built and fewer remain standing. Its deck has subsequently deteriorated and the bridge has been closed to traffic. The Eveland Bridge was listed on the National Register of Historic Places in 1998.
Completed in 1926 at a cost of $305,000, the Bell Street Bridge crosses the Yellowstone River in Glendive, Montana.
