Hoover Dam, Arizona-Nevada Switchyard, U.S. Highway 93, Boulder City, Clark County, NV

Significance: It is one of six switchyards built between 1935 and 1952 to provide terminals for major transmission lines carrying electricity to markets in California, Nevada, and Arizona. All of these facilities were built by the Bureau of Reclamation as elements of the Boulder Canyon Project, and Reclamation documents referred to the entire complex of switchyards as "Boulder Switchyard." The Arizona-Nevada Switchyard is therefore a contributing element of the switchyard complex that was a major feature of the Hoover Dam development and contributed to the historical significance of the complex.
