The Chesapeake & Delaware Canal (C&D Canal) is a 14-mile (22.5 km)-long, 450-foot (137.2 m)-wide and 35-foot (10.7 m)-deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States. The canal is itself a significant landmark and cultural boundary for the state of Delaware, considered a divide between the urbanized northern portion of the state and the rural southern portion known locally as "Lower Delaware", and demarcates an unofficial northern limit to the Delmarva Peninsula.
