The Dempster Highway, known as Yukon Highway 5 and Northwest Territories Highway 8, is a significant roadway in Canada, linking the Klondike Highway in Yukon to Inuvik in the Northwest Territories at the Mackenzie River delta. To traverse the Peel and Mackenzie rivers, the highway utilizes seasonal ferry services and ice bridges. The completion of the Inuvik–Tuktoyaktuk Highway in November 2017 established year-round access from Inuvik to Tuktoyaktuk, forming the inaugural all-weather road link between the Canadian road network and the Arctic Ocean. Named after William Dempster, a notable North-West Mounted Police (NWMP) officer famed for uncovering the fate of a lost NWMP patrol in 1911, this highway commences 40 km (25 mi) east of Dawson City, Yukon, along the Klondike Highway. It stretches 736 km (457 mi) in a north-northeasterly trajectory, traversing Tombstone Territorial Park and crossing the Ogilvie and Richardson mountain ranges, without encountering highway intersections or major roads along its path.
