 As the Trans-Canada route was composed of sections from pre-existing provincial highways, it is unlikely that the Trans-Canada Highway will ever have a uniform designation across the whole country.The Trans-Canada Highway, uniformly designated as Highway 1 in the four western provinces, begins in Victoria, British Columbia at the intersection of Douglas Street and Dallas Road (where the "Mile 0" plaque stands) and passes northward along the east coast of Vancouver Island for to Nanaimo.Short freeway segments of the TCH can be found near Victoria and Nanaimo, but the rest of the highway on Vancouver Island operates mostly as a heavily signalized low-to-limited-mobility arterial road that does not bypass any of its areas of urban sprawl, particularly Nanaimo and Duncan.
