Ferries
Prior to the construction of the causeway, Cape Breton Island was connected to the mainland by separate railway car and motor vehicle ferries.
In 1880, the Intercolonial Railway (ICR) was opened between Mulgrave on the Nova Scotia side, west to New Glasgow. In 1890, the ICR built a line from Point Tupper on the Cape Breton side, east to Sydney. As a result, a rail ferry service was necessary so that rail cars from Cape Breton Island could be interchanged with the mainland North America rail network. Initially a small 2-railcar barge was used, however the growth of traffic from Industrial Cape Breton soon mandated that a dedicated rail ferry service be established. This service was operated by the ICR until 1918 when the ICR was merged into Canadian National Railways (CNR). CNR operated the ferries from 1918 until the causeway opened in 1955. Vessels used included: Mulgrave (1893–1901), Scotia (1903–1955), and Scotia II (1915–1955).
Various private passenger and horse-drawn carriage ferry services operated between Point Tupper or Port Hawkesbury or Port Hastings to the Nova Scotia side. By the 1930s, the Nova Scotia Department of Transportation took responsibility for providing the automobile ferry service. By the 1940s, as a result of war-time travel growth, as well as the growing popularity of automobiles, the service was expanded to 24 hours/day. Toward the end of the service in the 1950s, vessels included the George H. Murray, John Cabot, Ponte de Canseau, and Sir Charles Tupper.
