This pony truss is noted for its use of v-lacing instead of cover plate on the top chord and end posts.
The Historic Bridge Inventory notes that a number of 1880s truss bridges in this area were designed by noted engineer Charles H. Latrobe, and suggests this bridge may have been a part of that design effort, although no records confirming that were noted. However, HistoricBridges.org compared this bridge to another bridge confirmed to be associated with Charles H. Latrobe, the New Bridge, and noted two uncommon details shared by these bridges. V-lacing on both bridges does not overlap. Meaning each lacing bar has its own rivet, and do not "share" rivets at each end with the next lacing bar. Rather, there are two rivets side-by-side, one for each bar. Also, the vertical members on both bridges have riveted plate on the sides, an unusual detail to strengthen the member. These details are unusual enough that it seems quite plausible that Charles H. Latrobe was involved with this pony truss.
The bridge has a significant number of rivets that were replaced with bolts.
