On Friday, May 29, Hoover Dam celebrates a unique anniversary. It will have been 85 years since the last of the concrete was poured for the project.
According to the Bureau of Reclamation, the dam alone contains 3.25 million cubic yards of concrete. Including the power plant, spillway tunnels and other equipment needed for it to operate, there are 4.36 million cubic yards of it at the structure.
“This was an incredible project,” said Mark Hall-Patton, administrator of the Clark County Museum. “It was the largest scale engineering project and yet they did it under time and under budget.”
