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 weaknesses in the old bridge were noted in 1887 and 1893. Both Des Moines and Lee counties financed the $5,110 construction of this bridge, which spans the Skunk River between the two counties. The 240-foot-long (73 m) Pennsylvania truss bridge was built in 1904 by the Clinton Bridge and Iron Works of Clinton, Iowa. It carried local traffic for nearly 90 years before it was closed. It has the distinction of being the longest pin-connected truss remaining in Iowa. The Bridgeport Bridge was listed on the National Register of Historic Places in 1998.
The Court Avenue Bridge is a historic structure located in downtown Des Moines, Iowa, United States.

The AJX Bridge is a historic Pratt truss bridge in southwestern Johnson County, Wyoming. The bridge was built in 1931 across the South Fork of the Powder River near Kaycee, Wyoming. AJX Bridge was built to provide a river crossing for U.S. Route 87. It was placed on the National Register of Historic Places in 1985 as part of a Multiple Property Submission devoted to historic bridges in Wyoming.
The Grand River Bridge is a historic bridge located west of Leon, Iowa, United States. It spans the Grand River for 235 feet (72 m). A 7-panel Pratt Pony truss spans the main channel of the river, with a 4-panel Pratt pony truss/bedstead and timber stringer that forms the approach span on the west side. It was built by bridge contractors Daniel and Webster for $2,980 and completed in 1890. The bridge is no longer in use for vehicular traffic. It was listed on the National Register of Historic Places in 1998.
The Wapsipinicon River Bridge is a historic structure located in Independence, Iowa, United States. It spans the Wapsipinicon River for 341 feet (104 m). The Buchanan County Board of Supervisors contracted with the Miller-Taylor Construction Company from Waterloo, Iowa, to build the new bridge on the south side of Independence for $37,680. However, high water created problems during construction, and the bridge was completed in January 1927 for $57,530. It replaced an earlier two-span iron truss bridge. This bridge is a concrete filled spandrel arch bridge with four spans. It was designed by the Iowa State Highway Commission, and continues to carry vehicle traffic. The bridge was listed on the National Register of Historic Places in 1998. There is a similar bridge upstream in Independence that was built in 1918.
Nodaway River Bridge is located west of Grant, Iowa, United States. It spans an arm of a small pond in Pilot Grove County Park for 70 feet (21 m). The Montgomery County Board of Supervisors accepted a petition from S. M. Smith to build a bridge over the Nodaway River south of Grant in June 1876, and another bridge over the Nishnabotna River at the same time. The county contracted with the Missouri Valley Bridge & Iron Co. of Leavenworth, Kansas, to design and build the Nodaway River bridge, which was completed later the same year for $1,000. The bridge consists of a single-span Bowstring arch-truss with a wood deck. It remained in use as a road bridge until 1968, when it was moved to the park for use as a pedestrian bridge. Even though it is no longer in its historic location and used for its historic function, the bridge was listed on the National Register of Historic Places in 1998 as an example of early transportation development in Iowa.
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.
The Okoboji Bridge is located southwest of Milford, Iowa, United States. The 83-foot (25 m) span carried traffic on 180th Avenue over a branch of the Little Sioux River. The Dickinson County Board of Supervisors hired a local contractor to build a bridge across the straits between East and West Okoboji Lakes in 1859. The wooden structures had to be rebuilt in 1874–1875. There was a desire for a drawbridge at this point to allow for steamboats to navigate between the lakes. Three different swing spans were built at this location in the 19th century. When the third span deteriorated the board of supervisors contracted with the Clinton Bridge and Iron Works of Clinton, Iowa to build a permanent span here in June 1909. The Pratt/Warren pony truss structure was completed later that year for $1,550. The bridge and the road were incorporated into the U.S. Highway System, and it was placed under the aegis of the Iowa State Highway Commission. In 1929 it was replaced with a fixed-span concrete girder structure. At that time the 1909 truss span was moved to Okoboji Township to span a branch of the Little Sioux River. It was listed on the National Register of Historic Places in 1998. The span has subsequently been abandoned.
Hale Bridge is a historic structure located south of Anamosa, Iowa, United States. It spans the Wapsipinicon River for 296 feet (90 m). It is an example of a bowstring through-arch truss bridge. Perhaps thousands of these bridges were built in Iowa in the late 1860s through the 1870s. However, by 1992, fewer than twenty survive.
