Bridge Documentation

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

Built in the 1930s, this is an early example of an all-welded truss bridge. Composed of rolled beams lacking the traditional v-lacing and lattice found in the riveted truss bridges which were more common in this period, it is essentially very similar in design and materials to welded truss bridges built today. While notable for documenting the early years of this type of truss bridge, it lacks the significance of riveted truss bridges since unlike riveted truss bridges, welded truss bridges continue to be built today, therefore this bridge is not an example of a disappearing structure type.

This bridge does appear to retain good historic integrity. The historic bridge inventory listed the following in the builder column: "STACY (WIDDICOMBE?)"

Information and Findings From New Jersey's Historic Bridge Inventory

Discussion of Bridge

The skewed 5-panel 1936 Pratt pony truss bridge is of rolled section welded construction. It is supported on random ashlar abutments. An uncommon detail is the connecting of the center-panel diagonals to a mid-panel gusset plate. Alterations are minimal and include outriggers and guide rail railings. Although the structure is a representative example of the pony truss technology, it is not individually eligible for listing in the National Register of Historic Places, nor does it currently contribute to an identified historic district.

Discussion of Surrounding Area

The bridge carries a lightly traveled rural road over a branch of the Neshanic River. It is located in a rural setting with nearby open fields and encroaching suburban housing development.
