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.
Information and Findings From New Jersey's Historic Bridge Inventory
Discussion of Bridge
The welded Warren pony truss bridge sits on stone abutments. The south abutment has concrete toe walls and wingwalls. Most of the members are rolled I-sections, but the bottom chord is built of two toe-out angles with batten plates and the end verticals are channels. The floorbeams and stringers are rolled sections as are the outriggers and railings. The bridge is one of at least 10 pre-1946 welded truss bridges in the state, and one of 3 over the same creek. The bridge is not technologically distinguished and is therefore not individually eligible for listing in the National Register of Historic Places. The bridge may be a contributing element of an historic district.
Discussion of Surrounding Area
The bridge is located in an area of scattered residential structures from the 19th century. The two-lane bridge carries a winding road over a stream near the intersection of two roads. The bridge was constructed by Welding Engineers Inc., of Philadelphia, who built three similar bridges over this creek. This is the earliest and largest of the three bridges. It replaced a 1882 pin-connected pony truss bridge that was built by Dean and Westbrook.
