The Confederation Bridge is a box girder bridge carrying the Trans-Canada Highway across the Abegweit Passage of the Northumberland Strait, linking the province of Prince Edward Island with the province New Brunswick on the mainland. Opened May 31, 1997, the 12.9-kilometre (8 mi) bridge is Canada's longest bridge and also the world's longest bridge over ice-covered water.
Construction took place from October 1993 to May 1997 and cost C$1.3 billion. Before its official naming, Prince Edward Islanders often referred to the bridge as the "Fixed Link".
The bridge is a two-lane toll bridge that carries the Trans-Canada Highway between Borden-Carleton, Prince Edward Island (at Route 1) and Cape Jourimain, New Brunswick (at Route 16). It is a multi-span balanced cantilever bridge with a post-tensioned concrete box girder structure.
Most of the curved bridge is 40 metres (131 ft) above water with a 60 m (197 ft) navigation span for ship traffic. The bridge rests on 62 piers, of which the 44 main piers are 250 m (820 ft) apart. The bridge is 11 m (36 ft) wide.
