This classic pony truss with heavy members contributes to the history of the Pennsylvania Railroad mainline. The historic bridge inventory lists "Pennsylvania Railroad and City Department of Public Works" as the builder, although they may have been the designers, it is not known who fabricated or erected the truss.

Information and Findings From Pennsylvania's Historic Bridge Inventory

Discussion of Bridge

The skewed, 1 span, 106'-long, rivet-connected Warren pony truss bridge built in 1924 is supported on ashlar abutments. The truss members are built up from standard steel sections. Built up floorbeams support rolled steel stringers and a concrete deck. Cantilevered sidewalks have original metal railings, but modern chain link fences have been attached. On the east side, a stairway has been built from the sidewalk to the busway. The bridge is a later example of its type and design that is not individually distinguished by its technology. The bridge's significance is in association with the development of the PHMC-determined eligible PRR Main Line. It dates from the line's period of significance and it is associated with efforts to improve the safety and efficiency of the line by improving grade crossings. The bridge was built as a joint project of the railroad and the city.

Discussion of Surrounding Area

The bridge carries a 2 lane street and 2 sidewalks over 2 active Conrail tracks and the Port Authority's East Busway. The setting is a mix of early 20th to late 20th century commercial and residential buildings. The railroad is the former Pennsylvania RR (PRR) Main Line, one of the most important transportation corridors in the nation. Originally 4 tracked, 2 tracks have been removed for the busway. The PRR Main Line from Philadelphia to Pittsburgh has been determined eligible by PHMC (DOE 9/14/93).
