Bonaventure sector

Visit the new bonaventurereconstruction.ca section to see this major project take shape between 2025 and 2029.

The Île des Sœurs Bypass Bridge was opened to traffic in 2014. This temporary structure was used as a detour while the new Île des Sœurs Bridge was being built for the construction of the Samuel De Champlain Bridge.

When the new Île des Sœurs bridge was commissioned on November 12, 2018, the temporary bypass bridge was disconnected from the road network. Now that it no longer needs to be used as a storage site for the deconstruction of the original Champlain Bridge or the construction of the REM, it can now be deconstructed.

Announcement of the Bonaventure Expressway reconfiguration project

The Honourable Pablo Rodriguez, Minister of Transport and Quebec Lieutenant along with JCCBI CEO Sandra Martel and Montréal Mayor Valérie Plante announce that the Bonaventure Expressway will be turned into a boulevard

In collaboration with École Polytechnique de Montréal, the Corporation carried out a research project to repair elements of this structure with ultra high-performance fibre-reinforced concrete (UHPFC).

The Solution Bonaventure is an environmental project to protect the St. Lawrence river against contaminant runoff from groundwater in the Bonaventure Expressway sector.

For over 100 years, from 1866 to 1966, The shore of the St. Lawrence River in the sector of the Bonaventure Expressway was used as a landfill site for industrial and household waste. Innovative solutions have been put forward to tackle a century of pollution.

A technological park was inaugurated on this land, called the Technoparc de Montréal (now the Pointe-Saint-Charles Industrial Park). The companies Teleglobe Canada (now Tata Communications), Bell Mobilité and Mel’s Cité du Cinéma are now established there.

The Corporation becomes responsible for the management, maintenance and monitoring of the Jacques Cartier Bridge, the Champlain Bridge and a section of Bonaventure Expressway, including the Clément Bridge.

A local aerodrome dedicated to short take-off aircraft was in operation along the Bonaventure Expressway.

The Bonaventure Expressway was built to create a third approach to the Champlain Bridge. It let motorists travel directly to the downtown core and became the main route to the Expo 67 site.

The Clément Bridge was inaugurated at the same time as the Bonaventure Expressway.

The Port of Montreal was responsible for the Clément Bridge from 1967 to 1977, which is why it was named after M. J. A. Clément, who was a bridge superintendent for the port authority.
