Walnut Street Bridge, Spanning Susquehanna River at Walnut Street (State Route 3034), Harrisburg, Dauphin County, PA

Significance: The bridge is a representative example of a late 19th century factory-manufactured roadway bridge. The bridge consists of 15 pin-connected wrought-iron Baltimore-type through-truss spans manufactured by the Phoenix Bridge Company, and utilizes that firm's proprietary column design known as the "Phoenix column." The Phoenix Bridge Company made important contributions to bridge design and construction in the late 19th and early 20th century.
