Bridge Documentation

Railroad pony truss bridges are not common. Shorter spans usually end up being some variety of plate girder and longer spans are usually through trusses. As a result, this is a significant, uncommon structure. A railroad pony truss is not just a rare find, it is an impressive find, especialy when it is carrying a deck that was originally designed for two sets of tracks. The trusses are massive to support the wide double-track railway! The bridge is a Pratt truss, and it features riveted connections. The gusset plates for the connections are so big, they are a third the height of the trusses!
