Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. The dam was named after President Herbert Hoover.
The dam was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt.
Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives.
The dam's generators provide power for public and private utilities in Nevada, Arizona, and California.
Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. The heavily travelled U.S. 93 ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.
The four-lane Hoover Dam Bypass opened on October 19, 2010. It includes a composite steel and concrete arch bridge, the Mike O'Callaghan–Pat Tillman Memorial Bridge, 1,500 ft (460 m) downstream from the dam. It is jointly named for Mike O'Callaghan, Governor of Nevada from 1971–1979, and Pat Tillman, an American football player who left his career with the Arizona Cardinals to enlist in the United States Army and was later killed in Afghanistan by friendly fire.
The bridge was the first concrete-steel composite arch bridge built in the United States, and it incorporates the widest concrete arch in the Western Hemisphere. At 900 feet (270 m) above the Colorado River, it is the second-highest bridge in the United States, following the Royal Gorge Bridge. It is also the world's highest concrete arch bridge. The Hoover Dam Bypass project was completed within budget at a cost of $240 million; the bridge portion cost $114 million (2010 prices).
