LaPlanche Street is the historic connector between Nova Scotia and New Brunswick, Canada. Located on the Isthmus of Chignecto, LaPlanche crosses the Tantramar Marshes between Amherst, NS and Sackville, NB. Historically, it hosted the key forts of peninsular Nova Scotia and continental Acadia and witnessed the Battle of Fort Beauséjour, the key battle between the two colonies during the Seven Years' War, and the Battle of Fort Cumberland of the American Revolutionary War.
