<Ul> <Li> Trans - Canada Highway </Li> </Ul> <Li> Trans - Canada Highway </Li> <P> The Trans - Canada Highway (French: Route Transcanadienne) is a transcontinental federal - provincial highway system that travels through all ten provinces of Canada from the Pacific Ocean on the west to the Atlantic on the east . The main route spans 7,821 kilometres (4,860 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 . </P> <P> Throughout much of Canada, there are at least two routes designated as part of the Trans - Canada Highway (TCH). For example, in the western provinces, both the main Trans - Canada route and the Yellowhead Highway are part of the Trans - Canada system . Although the TCH, being strictly a transcontinental route, does not enter any of Canada's three northern territories or run to the Canada--US border, the Trans - Canada Highway forms part of Canada's overall National Highway System, providing connections to the Northwest Territories, Yukon and the border, although the NHS (apart from the TCH sections) is unsigned . </P>
