Hoover Dam

The Hoover Dam was built on the Colorodo River and was expected to take 6 years. Frank Crow, who was in charge of the process of building of the dam, said that the dam would only take 4 years. There was enough concrete used in the dam building process that could make a 4 feet sidewalk to cover the Earth, there was an estamated 42,000 workers who showed up to help build the dam. Many people were helping build the dam, and proved that Frank Crow was right, and it only took 4 years to build. The dam has the line between the states Nevada and Arizona.
