Bonaventure sector

Bonaventure sector

As a main gateway to the city, this sector has a vital economic importance for Montreal. It includes the federal section of the Bonaventure Expressway as well as the Clément Bridge. The île des Sœurs bypass bridge is disconnected from the road network since October 2018.

JCCBI'S projects and sites

Massive structures like the Jacques Cartier Bridge or Bonaventure Expressway have many needs. They may require electrical repairs, paving, steel painting, and many other types of work. Most of these operations are planned in advance as part of JCCBI’s proactive asset management approach. Our Operations and Maintenance teams may also identify a need following an inspection or report, while user needs may change over time.
