Notes
  • Significance: The cast and wrought iron Pratt pony truss represents a rare survival of a design routinely applied in rural contexts throughout Franklin County in the 1870s. Although none of the earlier local bridges survive that the Mowersville Road Bridge resembles, the metal superstructure of the bridge is most likely similar to an older type that was developed and manufactured locally. These early Pratt truss structures were designed by the owners of foundries primarily engaged in the manufacture of agricultural implements and machinery. The sturdy, pragmatic forms of these bridges reflect the empirical practices of these local bridge builders, as well as early efforts at standardization in rural bridge design.
