The Nahanni Range Road was completed in the early 1960s from Watson Lake, Yukon along the present alignment of the Robert Campbell Highway to Miner Junction (aka Cantung Junction), thence along the Highway 10 route, across the border into the Northwest Territories to the privately owned mining town known, confusingly, as either Cantung (for Canada Tungsten Mining Corporation) or Tungsten (for the mineral mined there). The portion between Cantung Junction and Watson Lake has, since 1971, been part of the Robert Campbell Highway (Yukon Highway 4).
