This bridge is unusual because the top and bottom chords are both equally curved and thus remain parallel. The curving was done to increase clearance for trains without increasing substructure and approach work/costs.
The bridge has been well maintained. Rather than demolish this historic bridge, Hunterdon County has signalized the one-lane bridge to ensure that this one-lane bridge with notable issues with seeing opposing traffic on the other side of the bridge remains safe for the traveling public. This solution represents an effective way to ensure that historic bridges do not compete with the requirement and expectation that public roadways be safe, reliable, and functional.
Information and Findings From New Jersey's Historic Bridge Inventory
Discussion of Bridge
The 3-span bridge is composed of two short deck girder approach spans and a 6-panel riveted Warren with verticals pony truss main span built with curved parallel chords to increase clearance over the tracks. It is supported on concrete abutments and laced steel bents. Riveted outriggers are original. An expansion plate is located in the center of the span. Although there are no distinctive details, it is an unaltered example of a bridge type commonly used by the railroads since the 1890s. The structure is individually eligible for listing in the National Register under Criterion C.
Discussion of Surrounding Area
The bridge carries one lane of a lightly traveled 2-lane street over a single line of track of the Lehigh Valley Railroad now used as a Conrail freight line. It is located in a wooded village setting. Modern development is encroaching.
