This bridge is a pin connected Pratt half-hip pony truss. It was overgrown, and had been closed to traffic for many years. The southern truss was twisting slightly due to deterioration and damaged to the end post. There were small i-beams above the floor beams under the bridge. They appear to be added, perhaps to raise the deck. This bridge had the unusual detail of railings composed of wooden planks, attached to the vertical members with two bolts with a guide bar spanning between the bolts on the outside of the wooden plank. This type of railing appears to be an original detail of this bridge. This design of railing, using wood instead of metal, is very unusual among surviving metal truss bridges today. Bridges with this railing design either no longer exist or have had the original railing design replaced.
In order to save this bridge from continuing deterioration which would inevitably lead to collapse, HistoricBridges.org and Bach Ornamental and Structural Steel, got together and with the support of the Monroe County Road Commission, worked together to develop and execute a project to remove this and four other similar abandoned and deteriorated truss bridges in the county and place them into storage, ready for future restoration and reuse. The project was done without cost to the county, and HistoricBridges.org and Bach Ornamental and Structural Steel intend to recoup costs by restoring the truss bridges and selling them as like-new historic bridges to new owners.
