The Arch Bridge from the Boonton Ironworks crosses the Rockaway River in Grace Lord Park in the town of Boonton in Morris County, New Jersey. The single-span fieldstone arch bridge was built by John Carson Sr. in 1866 to carry a water pipe to the ironworks. It was added to the National Register of Historic Places on September 1, 2022, for its significance in engineering. It is currently used as a pedestrian bridge.[3]
