This is an interesting bridge. Tried to get some rough measurements on it, with the approaches in tact this one would've been close to 1000 ft long in service. The main truss span seems to be somewhere between 150-170 ft in length, perspective is a pain for this one but if I had to pin a number on it I'd say 160 ft for the main truss, then 440 ft for the northern approach and about 380-390 ft for the lost southern approach. Southern approach appears to have been removed sometime between the mid 70s to early 80s
I discovered this bridge (or, at least what certainly looks like a bridge) while tracking the L&N branch line from of Andalusia, AL. I checked my work using Google Earth, and the 1997 historical imagery does seem to support the existence of a bridge here, though I would love to have someone double check my work.
