I was in the area last week and had time to stop by.  There is an I-Beam across the road at the front of each bridge, and permanent markers in the road.  The road leading up to the bridge is paved but unmaintained, and has clearly been unused except for occasional property access for years.  The bridge is still there; pedestrian access is possible with great effort.  Not usable as a standard mode of transportation of any means.

I've updated to barrier=bar and set access=no.
