Nice work!
I've spent some time around some of these bridges. Here's a photo of "Bridge One" under construction in 1955-56:

The original swing bridge was basically single track (a gantlet/gauntlet) I can imagine what a bottleneck it was.
I was there a few hours after Penn-Central train OV-8 slammed into the counterweights of the raised bridge back in May of 1974. What a mess.
Good Luck, Ed
