Maybe it was just abandoned by the county and is privately owned. It isn't shown in the National Bridge Inventory.

Um..........im going to go out on a limb here and say that this bridge still exists. The bridge is still shown on Google Earth and there are many references to it being there on the internet. I have changed the status of the bridge to "open to traffic" unless someone can confirm the opposite. Perhaps this is like events in the show "Lost" but less dramatic except to bridgehunters like us. Maybe in 1993 the bridge fell into another dimension, yet to us it is still there.........sends shivers up my spine.

also noticed that there is no new listing for this county road on the NBI for a new bridge in 2000 or this years. Could it possibly be closed to all traffic and preserved in place?

I looked at a couple of different satellite images, which all show the bridge as being extant. And I'm sure these have all been taken since the 1993 date given for it's removal.

Jason, There is a Google Earth image dated Jul 7, 2007, for this location that indicates a single lane through truss bridge at this location. Impossible to tell if it the same bridge but the dimensions certainly match.
