BH Photo #351533
Anonymous,this is the bridge i mentioned that was north of the Tilghman Street Viaduct.Thank you for clearing this up.
Apparently the 2nd image is of the predecessor bridge. I'll make the changes when I'm able to access a proper terminal.
Not convinced these 2 photos are of the same structure.There were likely many RR spans in the Allentown area.
