Research by Dr. James Cooper has uncovered the significance of this unique structure. The design is referred to as "Iron Arch #1" by the Smith Bridge Company and is the only known remaining example of this type. The erection of this span was left to noteworthy Southern Indiana bridge builder William T. Washer of Troy in Perry County. He built a number of covered bridges using both his unique Burr trusses as well as building some Smith truss spans as an agent for that company. It is also documented that he built metal spans using Indiana Bridge Company trusses, and now we can add Smith iron trusses to the mix.
