Top of the Dam A walk along the sidewalks on top of the dam provides awe-inspiring views of the dam face, Lake Mead, the intake towers, the Colorado River, and other features around the dam site. The construction of the Hoover Dam, originally named the Boulder Dam, backed up the Colorado River resulting in the formation of Lake Mead. The dam was completed in five years. The contractors were allowed seven years from April 20, 1931, but concrete placement in the dam was completed May 29, 1935, and all features were completed by March 1, 1936.
Walking the Bridge In addition to driving on it, tourists will be able to park in a designated lot on the Nevada side and climb stairs to walk the bridge, which has a sidewalk on the side facing the dam. The retaining wall is 54 inches high, so pedestrians can snap photos from a spectacular vantage point.
