The fad for bathing in and drinking spring waters eventually passed. Local lore has it that the long-awaited construction of U.S. Route 41A through the town in 1940 caused the springs to dry up. The spa era passed by mid-century, and the hotels were razed. The new highway connected the town to sources of employment in neighboring communities, and gave it a strategic position on the main artery between Nashville and Chattanooga. The development of local lakes through dam construction by the Tennessee Valley Authority generated recreational business as well.
