Seal Island Bridge

Seal Island Bridge is a highway bridge that spans the Great Bras d'Or channel in Cape Breton, connecting communities across the water. The structure carries traffic across the channel with steel arches and concrete supports designed to handle regular vehicle flow.

Construction began in 1960 and the bridge opened in 1961, creating a permanent link across the channel where ferries once operated. This crossing replaced two established ferry routes that had connected the communities on either side of the water.

The bridge replaced two ferry routes, changing the traditional maritime transportation patterns of local communities and reshaping regional connectivity patterns.

The bridge undergoes regular inspection and maintenance to ensure it safely handles daily traffic. Drivers should be aware that strong winds can occasionally cause temporary closures for safety reasons.

Between 2001 and 2004, the bridge underwent major renovation and received a new precast concrete deck system that was recognized for engineering innovation. This modernization significantly extended the structure's lifespan and improved its performance through advanced construction techniques.
