This bridge is one of Hunterdon County's unusually large population of multi-span pony truss bridges. Multi-span pony trusses are uncommon in other parts of the country, where single span pony trusses are usually the only type of pony truss commonly found, with most multi-span truss bridges being through trusses.
The bridge has been altered with numerous welded additions to the bridge, but as a multi-span pony truss, it retains a degree of significance on a nationwide scale.
A little westbound down the road from the truss bridge is a tiny, but historically intact, attractive stone arch bridge. This bridge is not listed in the National Bridge Inventory, because it is under 20 feet in length and thus not considered a bridge by NBI.

Information and Findings From New Jersey's Historic Bridge Inventory
Discussion of Bridge
The traditionally composed pin-connected half hip Pratt pony truss is two spans, each 4 panels. It is supported on random stone abutments and a pier. Lattice railings remain. The bridge has been significantly modified. Welded additions include plates at panel points, reinforcing of the lower chords, repair plates on diagonals, and outriggers. On two panels the floorbeams are hung from the top chord using bolts and hangers. The span is too altered to be technologically significant.
Discussion of Surrounding Area
The bridge carries one lane of a lightly trafficked unimproved rural road over the South Branch of the Raritan River. It is located in a well preserved wooded setting that includes a camp and a nature preserve.
