British Columbia provincial highway 77, known as the Liard Highway, is the northeasternmost numbered highway in the province, and is the sole paved road connection between B.C. and the Northwest Territories. The highway officially opened to traffic in 1984, and was assigned the number 77 two years later. Highway 77 begins at a point on the Alaska Highway 28 km northwest of Fort Nelson , and it travels 138 km northeast along an expanse of flat land to where it connects with N.W.T. Highway 7, which the Liard Highway most likely takes its number from, at the 60th parallel.
