This bridge is open to the public not hard to find. It is just off the main road between Edinburgh and Ninevah which goes past the stoplight to main entrance to Camp Atterbury. Going west, cross the smaller bridge and just to the right is a tiny neatly constructed stone arch bridge. Cross it and the iron bridge is just up the road. The deck could use some attention. This road goes to what I believe is the Prisoners of War Cemetary. Anything not open to the public in Camp Atterbury is fenced off with No Tresspassing signs. I only gave directions because some county maps don't mark the Atterbury Fish and Wildlife roads.
This bridge must be in the middle of Camp Atterbury. I never could find exactly where the bridge is or if the public even has access to it.
