This bridge is one of a number of unusual pony truss bridges built by the Champion Bridge Company in Preble County well after the truss bridge era had come to a close in most of the country. They are noted for their use of modern design such as rolled beams and omission of any built-up beams, while continuing the older, traditional use of rivets for connections. The riveted connections are a contrast to the welded truss bridges that were built in Ohio around the same time as these bridges and continue to be built in the present day. The riveted connections add to the visual qualities of the bridges, compared to the plain-looking welded connections.
The 1950s and 1960s were the final home run of a transition from aesthetic bridge design to "purely functional" bridge design, where the "art" in bridge building came to a close thus ending a tradition of beauty in bridges. As a result, this bridge, with a 1958 construction date, represents the end of this transition. While it still has aesthetic value, mainly in the old-fashioned rivets, it is quite plain, with its rolled i-beams.
This bridge was missing a plaque at one end. Otherwise it is a traditionally composed example of this bridge design.
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, 73'-long, rivet-connected Warren pony truss bridge has polygonal upper chord and verticals. The members are rolled sections.
Summary of Significance
The ca. 1950 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.
