The Ashfork Bainbridge Steel Dam, the first large steel dam in the world, and one of only three ever built in the United States, was constructed in 1898 by the Atchison, Topeka and Santa Fe Railway (ATSF) to supply water for railway operations near Ash Fork, Arizona. It is named for the town of Ash Fork, and for Francis H. Bainbridge, a civil engineer and graduate of Rensselaer Polytechnic Institute (RPI), a member of the Rensselaer Society of Engineers, and an engineer for ATSF. The dam has been listed on the National Register of Historic Places since 1976.

The ATSF and other railroads had to make special provisions for water supply in desert conditions, as non condensing steam locomotives consumed a prodigious amount of water. The usual approach was to construct a dam to retain surface water, or to drill a series of wells, and store the water in a water tank. Railroad communities often grew up around these reservoirs or water stops. Ash Fork had been such a town from when the ATSF first arrived some years earlier although it had been a way point for stagecoach lines previously.

Railroads in the U.S. and elsewhere had been leaders in structural development. The masonry arch bridges and viaducts of the early 19th century had given way to bridges made mostly of steel, with considerable economy of material, construction cost, and time, and Bainbridge speculated that similar savings might be possible for dams. This dam was a significant departure from the more typical masonry construction. Already familiar with the construction of the ATSF's many steel bridges, Bainbridge decided to see whether steel construction could replace masonry in dams as well. The dam's light weight and prefabricated components must have made assembly easy relative to the laborious job of quarrying and setting stone.
