The Trans-Canada Highway (French: Route Transcanadienne; abbreviated as the TCH or T-Can, or simply the Trans-Canada) is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada, from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans 7,476 kilometres (4,645 mi) across the country, one of the longest routes of its type in the world. The highway system is recognizable by its distinctive white-on-green maple leaf route markers, although there are small variations in the markers in some provinces.
While by definition the Trans-Canada Highway is a highway system that has several parallel routes throughout most of the country, the term "Trans-Canada Highway" often refers to the main route that consists of Highway 1 (British Columbia, Alberta, Saskatchewan, and Manitoba), Highways 11, 17, and 417 (Ontario), Autoroutes 40, 25, 20, and 85 and Route 185 (Quebec), Highway 2 (New Brunswick), Highways 104 and 105 (Nova Scotia), and Highway 1 (Newfoundland and Labrador). This main route starts in Victoria, British Columbia and ends in St. John's, Newfoundland and Labrador, passes through nine of the ten provinces, and connects most of the country's major cities, including Vancouver, British Columbia; Calgary, Alberta; Regina, Saskatchewan; Winnipeg, Manitoba; Ottawa, Ontario; Montreal and Quebec City, Quebec; and Fredericton, New Brunswick. One of the main route's eight other parallel routes connects to the tenth province, Prince Edward Island.
