Chief dam engineer Frank T. Crowe lived up to his nickname, “Hurry Up” Crowe. The dam was completed two years ahead of schedule, in 1935.

Hoover Dam is 726 feet high, 45 feet thick at the top and 660 feet at the bottom, and is larger than the Great Pyramid of Cheops.

Hoover Dam is filled with 3.25 million cubic yards of concrete, enough to pave a strip 16 feet wide and 8 inches thick from San Francisco to New York City.
