Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

This bridge isn't the longest pony truss span around by any stretch, but as a half-hip pin-connected pony truss, its 70 foot length is relatively long. Likely due in part to this length, the trusses are unusually tall, making for an impressive view. The bridge has had galvanized girders with floorbeams added to the outside of the trusses.

Information and Findings From New Jersey's Historic Bridge Inventory

Discussion of Bridge

The 8'-high 5-panel Pratt half hip pony truss bridge is pin connected. It is supported on concrete abutments with wingwalls. The bottom chord is stamped eye bars and the top chord and end posts are built-up box members. Diagonals are also stamped eye bars. The floor system is new and the bottom chord has been patched and reinforced. Plates have been welded to panel points, but the pins and hangers remain. The undocumented span is too altered to be evaluated as significant.

Discussion of Surrounding Area

The bridge carries one lane of an unimproved country road over a minor stream in a lightly wooded rural setting near a working farm complex. It is near open fields and scattered houses.

Bridge Considered Historic By Survey: No
