Which did construction start on first, the Delaware and Raritan Canal or the Pennsylvania Canal?
Delaware and Raritan Canal The Delaware and Raritan Canal (D&R Canal) is a canal in central New Jersey, United States, built in the 1830s, that served to connect the Delaware River to the Raritan River. It was intended as an efficient and reliable means of transportation of freight between Philadelphia and New York City, especially coal from the anthracite fields in eastern Pennsylvania. Before the advent of the railroads, the canal allowed shippers to cut many miles off the route from the Pennsylvania coal fields, down the Delaware, around Cape May, and up along the (occasionally treacherous) Atlantic Ocean coast to New York City.
Easton–Phillipsburg Toll Bridge The Easton–Phillipsburg Toll Bridge is a bridge that carries U.S. Route 22 over the Delaware River. The bridge is between Easton, Pennsylvania and Phillipsburg, New Jersey, United States. The bridge opened on January 14, 1938, and is operated by the Delaware River Joint Toll Bridge Commission. The main river bridge consists of a 540 ft Petit through-truss span over the river; a 430 ft , five-span plate-girder viaduct at the New Jersey approach; and a 40 ft pre-stressed concrete boxbeam span over PA Route 611 on the Pennsylvania approach.
