Designer and mathematician Edwin Thacher designed the Clinch Avenue Viaduct on plans using the Melan system. Thacher also designed and built the Walnut Street Bridge, a series of camelback truss spans in Chattanooga, Tennessee. Knoxville rebuilt the Clinch Avenue Viaduct and altered it in 1981 for the 1982 World's Fair reopening it as a pedestrian bridge with a different railing, and reopened it to vehicular traffic in 2002.
