The route begins at the intersection of Route 1 in Deer Lake and ends in St. Anthony. Officially known as the Great Northern Peninsula Highway, it has been designated as the Viking Trail since it is the main auto route to L'Anse aux Meadows, the only proven Viking era settlement in North America. It is the primary travel route in the Great Northern Peninsula and the only improved highway between Deer Lake and St. Anthony. It is the main access route to the Labrador Ferry terminal in St. Barbe.
