Forget my earlier statement. This bridge is still in use. The one I was thinking of is further S on this road, crossing North River. Would be in Warren County.

I think Clover Hills Drive Bridge not be accessible anymore. The road has been barricaded about 2-3 mile S of overpass over Hwy #5. Walking access only?

Also barricaded at access coming from the South.
