Ashfork-Bainbridge Steel Dam, Kaibab National Forest

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 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, 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. ()
