CAUSEWAY, or CAUSEY, a massive construction of stone, flakes, and fascines; or an elevation of fat, viscous earth, well beaten; serving either as a road in wet marshy places, or as a mole to retain the waters of a pond, or prevent a river from overflowing the lower grounds. See ROAD.—The word comes from

the French Chaussee, anciently wrote Chaussee; and Causeway, that from the Latin Calceata, or Calcata; according to Sommer and Spelman, a calcando. Bergier rather takes the word to have had its rise à pedum calcis, quibus teruntur. Some derive it from the Latin calce, or French chaux, as supposing it primarily to denote a way paved with chalk-stones.
