Description 

Even though this bridge can be classified as a queenpost pony truss, I believe that an actual queenpost bridge is technically made of timber rather than metal, and a true queenpost lacks the diagonal members that exist in the center panel for stability. The wood bridges were typically made with heavy upper and lower chords to offset the lack of stability, and wood or metal diagonals were still added to increase payload capacity--the metal variations can also be classified as 3-panel Pratt pony trusses.
