From April to December 2025, planing and paving work will take place on the Clément Bridge, as well as rehabilitation of the abutments.
On the approach lanes we will be repairing concrete surfaces, replacing bearings, touching up paintwork and improving the drainage system. The overhead signage and streetlights in this sector will also be replaced.
One lane in each direction will be open on the Clément Bridge for the duration of the work.
The work involves the reconstruction of the road and the replacement of the drainage system, the lighting system and the supports of the overhead signage at Exit 5.
Exit 5 of the Bonaventure Expressway will be closed as of March 27, until the end of May. The detour will be via boulevard Gaétan-Laberge (Exit 4).
From April to December 2025, we will mainly be repairing the concrete slab of a portion of the deck, adding a higher performance waterproofing membrane and asphalting. The deck joints will also be replaced.
Two traffic lanes will be available at all times in both directions.
The Bonaventure Expressway was built in 1966. It is reaching the end of its service life and must be reconstructed. JCCBI will reconfigure the expressway into a boulevard with a 2+1 configuration in both directions. This project also includes improvements to the sector with a green corridor along the shoreline that will give residents closer access to the river. Two 2.5-km dedicated active mobility (cycling and pedestrian) paths will be added, as the sector does not currently have this type of infrastructure.
The path will be linked to the bicycle path network that is connected to the Île des Sœurs Bridge. This will allow cyclists coming from the Samuel De Champlain Bridge to reach downtown Montreal via the bicycle path that will be constructed along the boulevard.
Phase 1 will include the deconstruction of the Île des Sœurs bypass bridge and its approaches which is now almost complete. Some landscaping work will be held in 2025.
Phase 2 will include the section between Gaétan-Laberge Boulevard and the Victoria Bridge, with development work to begin in 2025 and end in 2029:
Work to deconstruct the Île des Sœurs bypass bridge was completed in 2024. Some landscaping work will be held in 2025. The land will be rehabilitated during the reconstruction of the expressway. This aspect is still being studied.
The Bonaventure Expressway was built in 1967 and is nearing the end of its service life. Pending its reconstruction as a boulevard in the coming years and to keep the structure reliable and safe, regular maintenance work is required particularly on the elevated lanes.
Most of the time, work in the sector of the elevated lanes is done on the box beams underneath the road surface. Since workers are under the lanes, the lanes must be closed so that traffic does not to impact the work.
The Solution Bonaventure is an environmental project to protect the St. Lawrence river against ontaminant runoff from groundwater in the Bonaventure Sector.
For 100 years, the shore of the St. Lawrence river was used as a landfill for industrial and household waste that has caused major contamination problems.
The Solution Bonaventure was launched in June 2016 and has been operating since 2018. The goal was to implement concrete solutions to prevent contamninants from flowing into the river.
