Walnut Street Bridge

Built in 1890, the 2,376-foot-long Walnut Street Bridge connects Chattanooga, Tennessee's downtown with North Chattanooga. The bridge's main spans are pin-connected Pennsylvania through truss spans. The top chord of these truss spans are configured in five sections, making the spans similar to the Camelback truss design. The bridge is historically significant as an extremely long and old example of its type; according to the Historic American Engineering Record: "The bridge was apparently the first non-military highway bridge across the Tennessee River."
