December 1938

Because of the hard times of the Great Depression, thousands of workers flock to the Pensacola Project site, making the small towns of Langley and Disney instant boom towns. Massman Construction of Kansas City (chief contractor on the dam project) begins pouring the first of 510,000 cubic yards of concrete. Driven by depression-era labor and surprisingly mild weather, the 24-hour-a-day continuous pour of concrete is completed 20 months later.
