In the early 1960s, the Trans-Canada Highway was built on the isthmus to connect with Nova Scotia and Prince Edward Island. Route 2 in New Brunswick and Highway 104 in Nova Scotia were built parallel to the existing Canadian National Railway trackage; this inter-provincial highway was upgraded to a 4-lane expressway in the 1990s. Route 16 in New Brunswick was built from an interchange with Route 2 in Aulac to the ferry terminal at Cape Tormentine. This was subsequently modified in 1997 to connect with the Confederation Bridge at Cape Jourimain.
