I shot this in April 2007. I just found your site and it an asset. I like to photograph covered bridges usually but when a neat iron bridge like this one catches my eye I will photograph it.
I am not sure if I can post my website address or not, just delete it if not allowed
I visited (and heavily photographed) this bridge as part of a traffic-signal-collectors meet the weekend of May 16th. One thing I noticed is that on the one end the bridge deck has a bad sag right before the abutment. It's almost like the heights didn't match up at the two ends so they "forced it to fit."
Also of interest in the area if you're interested, the park at Zoar Lake is in a derelict condition. Half of the park's building is literally on the verge of falling into the lake since the retaining wall holding it up has failed. The other half of the building was hap-hazardly torn down, leaving the roof cantilevered on one side, tile left from the bathroom, and the slab floor caved in from subsidence.
