This is a traditional 1920s riveted pony truss bridge. The original trusses retain good historic integrity and lack the major welded alterations seen on many other bridges in this county. On this one, welded alterations are minor. However supplemental rods were bolted into the bridge at the vertical members, this being the most notable alteration on the bridge.
At the time of documentation this bridge was being repainted. Hunterdon County is one of the only counties in the United States that actually properly maintains the paint systems on its many historic truss bridges. In the photos seen on this website, the bridge is silver because only the primer has been applied. The final top coat for bridges in this county is green.
Rivets are one of the most reliable fasteners ever created. Even bad ones still usually do their job. Even bad ones can perform for over 90 years. Look carefully inside the top chord of this bridge and you will see some rivets that were not fully driven. Yet the bridge has performed nicely for 91 years as of 2016.
Information and Findings From New Jersey's Historic Bridge Inventory
Discussion of Bridge
The 4-panel Warren with verticals pony truss bridge uses riveted plate construction. It is supported on concrete abutments. The top chord and end posts are built-up box member of channels with cover plate. Many welded repairs and alterations, including replacing the inside angle of the bottom chord with rebars and plates, diminish the integrity of the bridge. A late example of the over 25 county examples of its type, the span is not technologically or historically distinguished.
Discussion of Surrounding Area
The bridge carries one lane of a lightly traveled country road over a minor stream in a wooded rural setting near an abandoned mill. Scattered altered 19th-century houses are visible from the bridge. The setting is unspoiled.
