At the time the Hoover Dam was the largest construction project in the world only to be super-ceded by another Morrison Knudsen led project, the rebuilding of Pearl Harbor. The construction of the dam was lead by the Company along with 5 other construction partners for a much needed shot in the arm during the Depression.
Hoover Dam spans the Colorado River in Black Canyon between Arizona and Nevada, some 30 miles southeast of Las Vegas Nevada. Constructed in the 1930s, the concrete arch-gravity structure was intended to prevent flooding as well as provide much-needed irrigation and hydroelectric power to arid regions of states like California and Arizona. At 726 feet high and 1,244 feet long, Hoover Dam was one of the largest man-made structures in the world at the time of its construction, and one of the world’s largest producers of hydroelectric power.
More than 200 Morrison Knudsen engineers worked to design the dam that would be constructed in Black Canyon. It is the highest concrete arch dam in the United States, and the largest building project that the federal government had ever undertaken.
The Company employed over 6,000 people for the project.
