Public works and major projects

Last updated December 22, 2021

Montréal is responsible for only 30% of the construction projects taking place within its territory. The purpose of all this work is to provide the population with a quality road network, sustainable water and sewer systems and an enjoyable neighbourhood.

A new bike path, park improvements and maintenance of street and traffic lights are examples of projects we do manage. Some of them last only one day, while others must be planned in phases and stretched over time.

Major construction sites managed by the city

The major projects we undertake require significant human and material resources. They can take several months or even years to complete.

The most common types of major projects include:

  • Modernization of water and sewer systems
  • Construction of bridges and tunnels
  • Development of bicycle paths
  • Complete rebuilding of streets
  • Major urban renewal projects
