Notes
  • Significance: The structure is significant as a late example of a reinforced concrete arch design by the Philadelphia and Reading Railroad, and perhaps the longest such structure on the former P.R. system. Its design, falsework, and construction embody refinements developed during nearly 2 decades of experience with the material. The P.R.'s bridge also provides an important contrast to a nearby Pennsylvania Railroad bridge, reflecting the differing design philosophies of competing lines.
