FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY:
According to PADOT Dist. 8-0 environmental review records, the Marietta Avenue bridge over Amtrak has been determined eligible by PHMC. The skewed, single-span, rivet-connected Pratt pony truss bridge was built by the Pennsylvania RR. It is supported on stone abutments. PRR engineering department plans date the truss bridge to 1896. In 1960, the railroad strengthened the bridge with welded coverplates to the floorbeams, and welded attachments to the bottom chord and vertical members.
