Trivia: An entire city was created to house the builders of what project?
The Hoover Dam
Golden Gate Bridge
Correct Answer: The Hoover Dam
So why is this answer correct? : More than 20,000 men were contracted to help build the Hoover Dam, which was constructed between 1930 and 1936 . There were so many workers on the site that a full town, Boulder City, Nevada, was established to house them all. The federal government maintained control over the town for 30 years, until it was incorporated into the state of Nevada in the 1960s.
