Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 2-span, 136'-long, reinforced concrete, shallow elliptical arch bridge is supported on concrete abutments and pargetted bullnose pier with pilaster forming the parapet post at midspan. The intrados and spandrel walls have large spalls that have been patched with shotcrete. The paneled parapets have been cutdown to one-half their original height, and have been removed completely from the wingwalls. Loss of the railings is a significant alteration. Built in 1909 by the Ferro Concrete Co., the bridge is one of at least eight identified reinforced concrete arch highway bridges from 1909 to 1918 in Cumberland County, and one of over 270 pre-1920 examples statewide. Other less altered examples better represent the historical and technological significance of the early application of the reinforced concrete arch bridge technology in the county context (e.g. 21001100101523 & 21721305464014, the former built by the Ferro Concrete Co. in 1911).
