 These roads were upgraded in the 1960s as part of the Trans-Canada Highway project, with the Moncton-Amherst, Nova Scotia section being numbered Highway 2 and the Aulac-Port Elgin (and thence Cape Tormentine) section being numbered Highway 16.A cluster of highway service businesses established in Aulac, including a truck stop, several gas stations, motels and stores and the hamlet became a popular stopping point for highway travellers.During the 1990s, Aulac was bypassed when Highway 2 was upgraded on a new 4-lane alignment several hundred metres to the east.
