Which bridge linking Prince Edward Island and New Brunswick is the world’s longest over ice-covered water?

Confederation Bridge is the world’s longest bridge over ice-covered water.

The 12.9-kilometre bridge crosses the Northumberland Strait between Borden-Carleton in Prince Edward Island and Cape Jourimain in New Brunswick, Canada. It opened in 1997 after several years of construction and created a permanent road connection between the island and the mainland.

Its designers had to account for harsh winter conditions, including moving sea ice. The piers have ice-cutting shapes that help break and deflect ice as it presses against the structure. The bridge replaced a ferry service but does not charge tolls for travel into Prince Edward Island; tolls are collected when leaving the island.

Confederation Bridge is a road bridge, not a railway crossing. Its record describes the environmental setting of the crossing, rather than the overall length record for all bridges.
