I am heading this way coming to Indy next week. May have to stop.
This is actually an incredible find!
This appears to be a rare Columbia Bridge Works bowstring pony, which would make it ca. 1870's.
Definitely not the old South Fork Bridge though, which was longer and a through truss.
Nice find James!
I've inquired about using the image from panaramio
Just posted this bridge here. It was not previously listed and I know nothing about it. There seems to be no information regarding it, but it (according to the photo link I added) seems to be a real bowstring bridge. There is another bridge (http://bridgehunter.com/il/adams/south-fork/) listed in Adams county is a bowstring that I wonder could be this bridge, but the problem with it is that it seems to have overhead bracing and looks larger. Anyway, I need help here.
