This bridge was an otherwise traditional example of 1930s pony truss bridge construction. However, more recently, likely due to some sort of structural deterioration, the bridge has been retrofitted in the oddest of ways. Someone managed to acquire the girders from a through plate girder bridge and they attached them to half of the bridge. The girders do not run the entire length of the bridge, and a pier was added to support the end of the girder that extended into the water. Holes were cut through the deck of the truss bridge to connect the girder. There apparently must have been an issue with the floor beams or deck stringers at this end of the bridge to cause this alteration to take plate. The result is quite striking, and it is interesting to suppose that if this bridge were to be left and eventually restored, one might claim there were two historic bridges in one place here!
Information and Findings From Ohio's Historic Bridge Inventory
The bridge carries a 2 lane road over a stream in a sparsely developed, rural setting.
The 1 span, 87'-long, rivet-connected Warren pony truss bridge has polygonal upper chord and verticals. The members are built up. It appears that salvaged steel girders have been added to the inside of the truss lines as a strengthening measure (ca. 1990). There are lattice railings.
Strengthened with plate girders, ca. 1990.
Summary of Significance
The 1930 Warren pony truss is a late example of its type/design with no distinguishing features. It has riveted connections, typical of Warren trusses from about 1900 to the 1940s when riveted connections began
to be phased out in favor of welded connections. The weld-connected Warren trusses continue to be a popular bridge type/design on county roads in Ohio. The survey has identified more than 500 pre-1961 Warren pony truss bridges,
making them the most common truss type/design surviving in the state. This example is not historically significant for its technology or context. More distinguished examples better represent the significance of the type/design in
the development of the state's road systems. The not eligible recommendation of the prior inventory remains appropriate.
