where does the mackenzie river start and end
Mackenzie River Rising out of the marshy western end of Great Slave Lake, the Mackenzie River flows generally west-northwest for about 300 km (190 mi), passing the hamlet of Fort Providence. At Fort Simpson it is joined by the Liard River, its largest tributary, then swings towards the Arctic, paralleling the Franklin Mountains as it receives the North Nahanni River. The Keele River enters from the left about 100 km (62 mi) above Tulita, where the Great Bear River joins the Mackenzie. Just before crossing the Arctic Circle, the river passes Norman Wells, then continues northwest to merge with the Arctic Red and Peel rivers. It finally empties into the Beaufort Sea, part of the Arctic Ocean, through the vast Mackenzie Delta.[2][5][6]
Trans-Canada Highway From North Sydney, a 177 km (110 mi) ferry route, operated by the Crown corporation Marine Atlantic, continues the highway to Newfoundland, arriving at Channel-Port aux Basques, whereby the Trans-Canada Highway assumes the designation of Highway 1 and runs northeast for 219 km (136 mi) through Corner Brook, east for another 352 km (219 mi) through Gander and finally ends at St. John's, another 334 km (208 mi) southeast, for a total of 905 km (562 mi) crossing the island.[12] The majority of the Trans-Canada Highway in Newfoundland is undivided, though sections in Corner Brook, Grand Falls-Windsor, Glovertown and a 75 km section from Whitbourne to St. John's is divided.[12]
