This pony truss is noted for a few unusual details. In two areas, instead of pins, it makes use of threaded rod with nut connections, the two areas are at the end post connections with the top chord and also with the bottom chord. These details as well as the latticed verticals would make this look like the product of the prolific Wrought Iron Bridge Company of Canton, Ohio. However, upon closer inspection, a very unique detail on this bridge reveals that this bridge quite likely not the work of Wrought Iron Bridge Company. This bridge has very unusual cast iron rocker bearings. The end post sits on a rocker casting which in turn rests upon a curved cast iron bearing "plate." While the Wrought Iron Bridge Company did use cast iron rocker bearings, the bearing plates they used were always flat as seen with the Oak Street Bridge. The curved plate seen on this New Jersey bridge is something not found on that company's bridges, suggesting this bridge may be the work of a different company. If the 1899 construction date given for this bridge is accurate, this would also put the date of this bridge a bit past when the Wrought Iron Bridge Company was using these sorts of details.
Bearings are a detail often ignored with historic bridges, but if you visit this bridge take the time to check them out, as they are quite interesting, and the curved bearing plate design is almost like a work of art. A photo of the bearing is shown below.
Information and Findings From New Jersey's Historic Bridge Inventory
Discussion of Bridge
The skewed 3-panel Pratt half hip pony truss bridge is pin-connected with cast iron connectors. The west abutment is stone encased in concrete. The east abutment and wingwalls were rebuilt in concrete in 1955. The bottom chord is stamped eye bars with shop numbers. Many welded alterations, including plates on the top chord and the cast connections, additional diagonals, and outriggers. The cast details are found on better preserved bridges in the county. This altered span is not distinguished.
Discussion of Surrounding Area
The bridge carries one lane of a quiet country road over a minor stream in a wooded rural setting, near an 18th-century mill converted to a house. The surrounding area is residential with scattered houses dating from the 18th through the 20th centuries.
