Note: The truss portion of this bridge has been listed as an approach span. This bridge is so unusual the HistoricBridges.org database was unable to classify the bridge any other way, since it is essentially two different bridge types merged into a single span. Length given is an extremely rough estimate.
This bridge serves a private driveway, but is located right next to a public road. At first glance this looks like a noteworthy pin-connected pony truss. Although they have been broken off, the tops of the end posts once held little plaques that would have credited the Canton Bridge Company of Canton, Ohio with building the trusses. These plaques would have doubled as splice plates between the top chord and end post cover plates. These trusses are significant as examples of bridges built by this noteworthy bridge company. However, these trusses are in reality not the actual bridge. Looking under the bridge, the true bridge is discovered. Less attractive, but far more rare and historically significant, the actual bridge is the last known original surviving example of a patent plate leg girder bridge which was a design built by the Indiana Bridge Company of Muncie, Indiana. The trusses have been welded on to the sides of these girders, perhaps for decoration and to function as railings. The girder bridge is extremely rare and significant as a last survivor of an in-state bridge builder's unusual patented bridge design.

Statement of Significance
A prolific Hoosier firm patented the design or pattern for this bridge. The oldest "plate leg" girder in the state--and one of the earliest fabricated--retains its original members. The Indiana Historical Society Library has drawings which the company may have used to fabricate this bridge.
The Indiana Bridge Company of Muncie patented its "plate leg" girder in 1886. This example is now seated behind concrete abutments and wingwalls. The single-span girder extends 45' in three panels. The center panel consists of a rectangular plate about 2' high; the outer panel is flared (or about double its height) toward/at the abutment. The flange ends are square and not reinforced with cover plates. Bolted to the plates near the ends of the center panel plate, two I floor beams support the asphalt-over-timber deck with its 15'3" roadway.
