Troy that sounds like a disaster waiting to happen haha.
The old bridge across the river in charleston sc was all metal and the road surface was grating so you could see through it, it was rusted to hell from the saltwater and about as narrow as you can get a full size car through. It was not really fun to cross, and terrifying on a motorcycle for some reason.
But that one is in a state park and really well maintained the roads around it are pretty sweet, that part of tn reminds me of West Virginia actually
