The Canso Causeway is a vital bridge and causeway that connects the mainland of Nova Scotia to Cape Breton Island in Canada. Completed in 1955, it spans approximately 1.5 kilometers (0.9 miles) across the Canso Strait, facilitating transportation and trade between the two regions. The causeway is a crucial link for both local residents and tourists visiting Cape Breton. In addition to its practical use, the Canso Causeway features a lock system that allows for the passage of boats and ships. This engineering marvel plays a significant role in the economy of the area, supporting industries such as tourism and fishing, while also providing access to natural attractions like the Cape Breton Highlands National Park.
