FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
The one span, 109'-long, pin-connected, Pratt thru truss bridge was fabricated in 1885 by the Pittsburgh Bridge Company. The bridge is one of six identified truss bridges (ca. 1870-1924) in Franklin County, and the only Pratt thru truss. The bridge, composed of standard built-up sections, has no significant alterations. It is supported on stone abutments with flared wingwalls. The Pittsburgh Bridge Company, established in 1878, was a successful fabricator and marketer of bridges in the state in the last two decades of the 19th century. The company had an important Franklin County connection in Thomas M. Nelson of Chambersburg, who operated as an agent contractor for the erection of the company's bridges beginning in 1883, and served as the company president from 1896 to 1900. The bridge is historically and technologically significant in the context of late-19th-century metal truss bridges in Franklin County.
