The 2-span 4-panel Pratt half hip pony truss bridge is supported on ashlar abutments. Although it was built in 1903 by the Dover Boiler Works of Morris County, New Jersey, a small local fabricator that built a few bridges between 1901 and at least 1904, the bridge is not eligible. It has been strengthened and repaired at least twice (1938 and 1978), and as a result it has no integrity of original design. It was originally pin-connected. Little original/early fabric survives. The bridge is located within the designated National and State River Road Historic District.
