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

This bridge is so severely altered, you might think it is actually a newer bridge merely built from parts. However, it apparently is a severely altered representation of the actual bridge that has been here since a pin-connected truss bridge was built here, presumably in the late 1800s. This bridge today offers little in terms of historic value due to its alterations, but its worth noting just because it is so comical to look at and see what happened to it. The other ironic element is while other less altered truss bridges in the county have had original floor beams replaced, this one actually retains original built-up floor beams! The alterations to this bridge included primarily turning a pin-connected truss bridge into a truss connected with welded gusset plates. All pins were removed, and only some pin plates remain. New gusset plates were welded in. The u-bolts were apparently welded to the floor beams during construction, then all but the vertical portions of the u-bolts were cut off. You can see the vertical portions remain welded to the floorbeams. All eyebar heads were cut off and the remaining bar welded to the gusset plates. Welded outriggers were added. Beams similar to railroad crash bars were added running from the hip lower connection to the end posts. These apparently came from another truss bridge. These salvaged beams are riveted and originally had cover plate, but this was torched off and portions of the rivets remain.

Information and Findings From New Jersey's Historic Bridge Inventory

Discussion of Bridge

The 4-panel Pratt pony truss bridge is supported on random fieldstone abutments with wingwalls. Concrete collars and patches were added in 1964. Circa 1960, the original connecting pins were removed and replaced with welded gusset plates. Outriggers and metal guide rail were added. The alterations have seriously compromised the design integrity of the bridge, making it less historically and technologically significant than some of the over 10 other Pratt full hip pony trusses in the county.

Discussion of Surrounding Area

The bridge carries one lane of a quiet unimproved rural road over a minor stream. It is located in a rural area of open fields, pasture land, and modern farm buildings.
