1964 Map of Knoxville

Industrial and hydroelectric development is visible through the prominent reservoir systems of the Tennessee Valley Authority, such as Douglas Lake and Fontana Lake. Urban centers like Knoxville and Asheville appear as concentrated hubs connected by the Southern and Clinchfield railroads. This era's infrastructure is defined by primary routes like U S 441 and the early segments of Interstate 40, which cut through the gaps of the Bald Mountains and Unicoi Mountains.
