Awesome; this is an in the future project but I was curious; I want to try to hit the full length of the bridge for a future layout which is still in my head, but it could end up being too big, so if it gets selectively compressed, I'll probably still go for 6 spans. what's really neat is the abutments are double track, but they ripped the double track out a while back.
I'm not sure if the spans are all the same length but to my eye they are (whenever I go to church or up to the campus beach I cross another bridge that has a far-off view of this bridge). Thanks for the encouragement fellas!
