Significance: The Six Mile Run Calvert is an integral part of the Delaware & Raritan Canal's (hereafter D&R Canal) early nineteenth-century engineering design. The culvert's original construction remains largely intact and consists of three 130-foot-long stone masonry barrels that carry Six Mile Run beneath the canal prism. Built between 1830 and 1834, the D&R Canal is an excellent example of early nineteenth-century American canal technology. In 1973, the D&R Canal, including Six Mile Run Culvert, was placed on the National Register of Historic Places.
