Did you know Arizona is home to some impressive engineering marvels? That’s right! Our bridges, canals, buildings and other structures are among some of the most innovative engineering projects for their day. One such place? Hoover Dam.

Construction on Hoover Dam began in 1931 to control the flow of the Colorado River and to provide a source of hydroelectric power for Arizona, California and Nevada. Construction finished in 1936 and since then, it has become a major tourist attraction for the area for the beauty of the dam’s engineering and for containing the country’s largest reservoir, Lake Mead. I think most of us have visited the dam at least once in our lives—and for those of us old enough to remember—even slowly drove over the top of the dam on U.S. 93. Let’s take a look at what construction of this marvel looked like!
