world's longest national road, extending east-west across the breadth of Canada for 4,860 miles (7,821 km), between Victoria (Vancouver Island, British Columbia) and St. John's (Newfoundland), linked by car ferries between Prince Edward Island, Nova Scotia, and Newfoundland. The highway passes through all 10 Canadian provinces, links many leading Canadian cities, and provides access to important national and provincial parks. Authorized by the Trans-Canada Highway Act (1949), it was dedicated Sept. 3, 1962, at a ceremony in Rogers Pass in Glacier National Park, British Columbia. Not until 1965, however, when a 200-mile (320-kilometre) stretch was completed in Newfoundland, were motorists able to drive the fully paved route between the Pacific and Atlantic coasts.
