This bridge is a plate girder bridge. All but the ends of the original pipe railings have been removed. Builder plaques remain on the remaining ends of the original railings. The top of the bridge is today unsightly, with cyclone fencing, no original railings, and modern Armco guardrail. Beside the bridge however, the girders and supports including built-up steel bents and stone abutments are largely unaltered and represent the bridge type well. The bridge is noteworthy because of its continuous design as opposed to using simple spans. It also contributes to the historic Pennsylvania Railroad mainline, which the bridge crosses.
Information and Findings From Pennsylvania's Historic Bridge Inventory
Discussion of Bridge
The 3 span, 145' long and 26' wide, built up deck girder bridge has a 61' long span over the railroad tracks and 38' long approach spans. The substructure consists of ashlar abutments and built up steel column bents. The floorbeams are built up, and the stringers and deck are wood. The original 4 rail high metal pipe railing remains on the west side. It has been replaced with beam guiderail railings between the road and the sidewalk and a chain link fence on the sidewalk's other side. The builder's plaque is in the original railing end post. Although an example of a common bridge type, the bridge is historically and technologically significant for its association with the Pennsylvania RR main line.
Discussion of Surrounding Area
The bridge carries a 2 lane street over 2 active railroad tracks and an access road. The line, now a Conrail line, is the former main line of the Pennsylvania Railroad that PHMC has determined eligible. The surrounding area of North Irwin is a mix of early 20th century houses and modern structures, both residential and commercial. The area does not have the consistency or cohesiveness to be a historic district.
