 This bridge was horse-operated and according to Canadian yachtsman and author Silver Donald Cameron, a former resident of D'Escousse) in his book "Wind, whales and whisky" (page 14), was powered by Stanley Forgeron's rather temperamental horse in 1967 when Farley Mowat sailed through the passage aboard "Happy Adventure" on his way to Expo67.In February 1970 following the grounding and subsequent breakup of the Liberian-registered tanker Arrow  on Cerberus Rock in Chedabucto Bay and the resulting spill of 77,000 to 82,500 barrels (more than 2 million gallons) of bunker C oil, the decision was made by the Nova Scotia Government to construct two causeways between Burnt Point and Burnt Island  to stop the spread of the Arrow's spilled cargo into the lucrative fishing areas of the Passage as well as the coastline to the east.After the oil spill cleanup by the mid-1970s, the Government left one causeway in place because the 1919 bridge had rusted beyond repair and in response to the needs of marine interests built the Lennox Passage Bridge, a four-span, bascule bridge with two concrete spans, a counterweight span and an electrically powered single-leaf bascule bridge carrying Nova Scotia Route 320.
