The Hoover Dam is an iconic man-made wonder that has been attracting tourists from all around the world for decades. The construction of this modern marvel was a notable time in Nevada’s history. At the time, Las Vegas was a small city of just over 5,000 people. This was during the Great Depression so the project attracted thousands of workers to the area. There’s no telling what Nevada would look like today if the Hoover Dam hadn’t come to fruition. Taking only five years to complete in between 1931 and 1936, the dam was one of the largest and most incredible construction projects in U.S. history. We’ve compiled 10 amazing photos of the dam’s construction which are sure to fill you with nostalgia for the Silver State’s early days.
