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.
Clinton–Kalamazoo Canal The Clinton–Kalamazoo Canal is a canal in Michigan that was abandoned after being only partially completed. The canal was to connect Lake St. Clair with Lake Michigan. Project backers were inspired by the success of the Erie Canal in New York, which was completed in 1825. After gaining statehood in 1837, Michigan elected its first governor, Stevens Thomson Mason, who initiated an ambitious program of internal improvements, including three railroads and two canals.
