This bridge is the only known surviving example of an Indiana Bridge Company patented cantilever leg bridge. The bizarre bridge design is unlike anything every known to have been built by any other company. The design featured a Warren deck truss with a cantilevered design. The ends of the trusses were attached to legs that extended below the bottom chord to form a substructure, which is the bedstead aspect of the design. This bridge represents the design perfectly and a drawing from the Indiana Bridge Company shown below outlines a truss with the same member arrangement as this bridge. This bridge also features a historic rivet-connected Warren pony truss span. The two spans may have different histories, original locations, or construction date. For example, the pony truss may have been relocated to this site at a later date to replace a previous span. The exact history here is not known.

This bridge has been abandoned. The deck truss nature of the bedstead span is allowing flood debris to build up. The bridge is therefore at risk for destruction by floods. This is the last known example of a highly unusual patented bridge type. It should receive the highest preservation priority. This would be a good candidate for relocation and preservation in a new location, perhaps in a park or on a trail for pedestrian use only.

Indiana Bridge Company produced a number of unusual small-scale cantilever/bedstead bridge designs. Another example is a plate girder variation.
