As a main gateway to the city, the Bonaventure sector has a vital economic importance for Montreal. It includes the federal section of the Bonaventure Expressway as well as the Clement Bridge.
Recently, 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 Clément Bridge connects the Bonaventure Expressway to Île des Sœurs and the Samuel De Champlain Bridge. Its total length is 334 m, its width is approximately 20.5 m, and it has two traffic lanes in each direction.
The Bonaventure Expressway was built to create a third approach to the Champlain Bridge. It was also meant to let motorists travel directly to the downtown core, and it became the main access road to the Expo 67 site.
The Clément Bridge, which connects the Bonaventure Expressway to île des Sœurs and the Samuel De Champlain Bridge, has eight spans, each consisting of thirteen precast prestressed concrete beams.
As the Bonaventure Expressway is over 50 years old, JCCBI has implemented several repair programs on this structure over the years, both on elevated and non-elevated sections.
The work on the non-elevated sections is undertaken to keep these sections safe until they can be replaced. Work on the elevated sections, which will remain in place for a longer period, is being done to ensure their integrity.
