Happy Valley was a construction camp of trailer homes and hutments at the Clinton Engineer Works of the Manhattan Project in the 1940s. It was located near the K-25 gaseous diffusion plant in Oak Ridge, Tennessee , to lessen travelling time for the seventeen thousand construction men working there.[1]
The Happy Valley settlement was dismantled in the early 1950s.
