One of the first jobs to begin building the Hoover Dam was to get the men and machinery down to the dam site. To do that, they had to bore through some of the toughest rock on earth in order to get the train tracks to the job site. Blasting the tunnels was one of the most dangerous jobs on the project and most of the men who died building the dam died inside these tunnels.
Las Vegas was a two-hour car ride away. Boulder city was a “company town” it was only for the white workers who were building the Dam. The minority workers lived in what was called Ragtown, just outside the tunnel entrance.
