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 Historic Bridge Inventory listed "M B CULVER, DIR" as the designer for the bridge. A builder is not known.
Rivets on this bridge have flat heads and cone-shaped heads, which is different from the usual round head seen on most metal truss bridges.
This bridge has had modern girders added to support the weight, which either reduces or eliminates the function of the truss. This results in a significant loss of historic integrity.
Information and Findings From New Jersey's Historic Bridge Inventory
Discussion of Bridge
The 2-span pin-connected Pratt half hip pony truss bridge is supported on random stone abutments with wingwalls and a stone pier. Each span is 4 panels. Numerous welded repairs and reinforcing mar the integrity of design. They include additional cover plate to the top chord and verticals, plates at panel points, and reinforcing to bottom chord, additional diagonals, and new floorbeams. One of over 20 Pratt halfhip pony truss bridges in the county, the altered bridge is not distinguished.
Discussion of Surrounding Area
The bridge carries one lane of a lightly traveled country road over the Musconetcong River, the county line with Warren County. The bridge is located in a lightly wooded park-like setting that is maintained by a conservation club. The river is channeled by stone weirs upstream. A sharp bend in the road marks the Warren County approach to the bridge.
