Thanks to Rick McOmber for visiting and photographing this bridge.
This bridge was originally known as East Townline Bridge. Recently it also had yet another nickname of simply Old Iron Bridge. www.oldironbridge.com had this bridge listed as a King Bridge Company structure, but it is unclear where that came from, as their is no plaque for the bridge. The plans on their website do not appear to match this structure. Either way, although this is a small bridge overall, for a two-panel half-hip Pratt pony, it is quite long. In other words, the panel size is above average. The bridge no longer functions as a truss bridge, because a pier support has been added in the center. The bridge today functions as a steel stringer, with only the deck stringers supporting the deck, and in the national bridge inventory actually shows up as a metal stringer. However, the bridge is still an attractive crossing, and was the subject of attempts at preservation made a few years ago. The bridge was apparently going to be abandoned and turned over to private ownership. No actual work was ever done on the structure however.
