Confederation Bridge

The Confederation Bridge is a massive engineering feat in Canada.

It carries the Trans-Canada Highway across the Abegweit Passage. This passage is part of the Northumberland Strait. The bridge connects Prince Edward Island to the mainland province of New Brunswick. It holds the title of Canada's longest bridge. It is also the longest bridge in the world built over ice-covered water.

The bridge uses a complex structural design. It is a multi-span balanced cantilever bridge. This means the bridge sections extend outward from central supports. It features a post-tensioned concrete box girder structure. These are large, hollow concrete beams that are strengthened using high-strength steel cables.

The structure rests on 62 piers in the water. Among these, 44 are the main piers. Most of the curved bridge stays above the water level. However, a specific navigation span is included. This span allows large ships to pass underneath safely.

Building this bridge required immense planning and resources. French engineer Jean M. Muller designed the structure. He was a specialist in multiple span match-casting bridges. Construction began on November 1, 1993. The work continued until May 1997. The total cost for the project was C$1.3 billion.

Before it received its official name, residents often called it the "Fixed Link." The bridge officially opened to traffic on May 31, 1997.

Traveling across the bridge is a relatively quick process. It is a two-lane toll bridge. It links Borden-Carleton in Prince Edward Island to Cape Jourimain in New Brunswick. Driving across the bridge takes approximately 12 minutes at the speed limit. The speed limit can change based on wind and weather. While pedestrians and cyclists cannot cross the bridge, a shuttle service is available.

This shuttle service has had different costs over the years.

Using the bridge involves specific toll rules. Tolls only apply when travelers are leaving Prince Edward Island. For a long time, the toll for a two-axle car was $35. By January 1, 2022, the rate had increased to $50.25. This increase followed yearly inflation rates. The Federal Government later provided subsidies to freeze these rates. Following a promise made during the 2025 federal election, the toll was reduced. Effective August 1, 2025, the toll dropped from $50.25 to $20.

This change was part of a campaign by Mark Carney.

Before the bridge existed, people relied on water transportation. Proposals for a permanent link date back to the 1870s. During that time, steamships connected the Island to the mainland. In the winter, steamships often struggled with sea ice. Some travelers even used iceboats to move mail and people.

A dedicated railcar ferry service began in 1915. This service operated for many decades. It was managed by various groups, including the Canadian National Railway and Marine Atlantic. Eventually, the government decided a bridge was a more reliable solution.

The idea of a fixed link faced many challenges. In the 1960s, a plan for a causeway was rejected. Experts feared the tidal regime in the Northumberland Strait. The strait has very complex tidal cycles. Experts at the Canadian Hydrographic Service noted that currents through a gap could be extremely powerful. These currents might be strong enough to sweep away boulders the size of houses. In 1988, a plebiscite was held to let citizens vote. About 59.4% of voters supported the fixed link. This vote helped move the project toward its eventual construction.
