The Fort Madison Toll Bridge is a tolled, swinging truss bridge over the Mississippi River that connects Fort Madison, Iowa, and unincorporated Niota, Illinois. Rail traffic occupies the lower deck of the bridge, while two lanes of road traffic occupy the upper deck. The double-decker bridge, about a mile long with a swing span of 525 feet (160 m), 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.
