Construction of the Hoover Dam- in pictures

- Advertisement -

Often called as one of the marvels of engineering, the Hoover Dam is a sight to behold. This massive concrete dam is located in the Black Canyon of the Colorado River and was constructed between 1931 and 1936. The construction of Hoover Dam was an engineering feat and took meticulous planning.

Let us take a look at the construction of the Hoover Dam- in pictures

1) A group of people are inspecting the proposed site of the dam in the Black Canyon.

4) The ‘high-scalers’ hammering anything loose. Additionally, the falling rocks were dangerous hence these men covered their hats with tar and left them out to dry; essentially creating the first hard hats.

5) The construction of the Hoover Dam required a special steel bucket machine that would transport concrete deep within the tunnels.

10) One of the unique equipment used for the construction of the Hoover Dam was the ‘drill rig’. Here workers are posing with the ‘jumbo rig’, which allowed multiple drillers to work together.
