(
Bridge Hunter, no Historic Bridges,
3D Satellite)
I found this bridge because UP provided the wrong city for
a bridge in their article about using drones to inspect bridges. I can't decide if it is a trunnion bridge with an unusual rack design or a rolling bridge with a rolling member that is not a circle arc so the rack is not straight. Either way, it is the first time I have seen a bridge like this. Too bad it is unused and we won't see any pictures of it in the down position. Seeing a "down" picture would give us a better clue as to how it works.
