I know there are a few left, most were destoryed when the germans left them. My great granddad has film of ww2 and i saw a couple of bridges in there. I'll see what I can do , also I believe a couple if not 1 or 2 are still intact on Normandy. Either around Carentan,Culoville, or Sainte Marie du Mont.
Bridge at Remagen. Ive got a buddy who went there as part of a tour to see where his Dad had been. He said the Museum was nice. he went to the other side of the river though,climbed down, and said those towers are in disrepair. Came home with a few bricks he showed to me. I've actually got a small chunk somewhere in my office.
