The Higginsville Road Bridges, spanning the South Branch of the Raritan River between Somerset and Hunterdon counties, represent an important part of nineteenth-century transportation, engineering, and technology in America. They are two of only eight Pratt, half-hip through bridges surviving in the state and remain relatively unaltered. The north span was cast in 1890 by Milliken Bros. and is the most complete and rare fabrication by this casting company. The south span, cast in 1893, is one of the few examples of the work of the Wrought Iron Bridge Co. The bridges have served as landmarks in this scenic landscape for over one hundred years.

The grant funds the repair and reinforcement of the trusses to handle the weight of modern road traffic. The structures will be cleaned and painted and repairs will also be made to the stone abutments and retaining walls.
