Situated in the Bay of Fundy immediately southwest of the Digby Neck, Brier Island is located immediately west. Long Island is separated from the Digby Neck by the "Petit Passage" and from Brier Island by the "Grand Passage". Route 217 runs the length of Long Island from the ferry crossing at Tiverton at the eastern end of the island (connecting to East Ferry on the Digby Neck) to the ferry crossing at Freeport at the western end of the island (connecting to Westport)
