That road has a sign indicating that it is impassable during high water.

Description 

The existing steel stringer bridge is almost certainly not the 1880 bridge or a 1980 rehab of it. I used the NBI data because I don't yet have information on what the original 1880 bridge was. It was probably an iron truss bridge.
