Trunk 2 is part of the Canadian province of Nova Scotia's system of Trunk Highways. The route runs from Halifax to Fort Lawrence on the New Brunswick border. Until the 1960s, Trunk 2 was the Halifax area's most important highway link to other provinces, and was part of a longer Interprovincial Highway 2 which ended in Windsor, Ontario. The controlled access Highway 102 and Highway 104 now carry most arterial traffic in the area, while Trunk 2 serves regional and local traffic.
