It was dug from 1793 to 1805 by a private company and has been rebuilt many times since.","why_significant":"The nomination argues the canal was an early, major engineering achievement and a key inland link between southeast Virginia and northeast North Carolina. It supported commerce, transportation and maritime history, and later became part of the Atlantic Intracoastal Waterway. It also spurred growth such as that of Elizabeth City, and its operation has been nearly continuous for over 180 years despite many changes.","narrative":"Running 22 miles between Deep Creek, Virginia, and South Mills, North Carolina, this canal cuts along the edge of the Great Dismal Swamp. Authorized by Virginia in 1787 and ratified by North Carolina in 1790, it was dug by hand from 1793, with the through cut completed in 1805. A Feeder Ditch added in 1812 draws water from Lake Drummond to supplement navigation. Private companies widened, deepened and reduced the number of locks before the federal government bought the canal in 1929. Its present locks, bascule drawbridges and spillways date from the 1930s to the 1960s. The canal was an early inland waterway linking Hampton Roads with Elizabeth City, carrying shingles, lumber, cotton and passengers, and it visited by Presidents Monroe and Jackson. It faced competition from the Albemarle and Chesapeake Canal, which opened in 1859. Today it forms an alternate route of the Atlantic Intracoastal Waterway, used mostly by pleasure boats, and its long, changing operation underlies its listing.","period_of_significance":"1787-1861, 1866-1892, 1892-1912, 1913-1929, 1929-1941","architect_builder":null,"architectural_style":"No style","criteria":["A","C"],"status_note":"Still in operation, run under contract to the Corps of Engineers eight hours a day, seven days a week.
