Installed in 1904, the secondary water line located below Rue Sainte-Catherine East is reaching the end of its useful life. The same is the case for the sewer lines below Rue Sainte-Catherine Est and Rue Adam, as well as for Avenue Bennett and Avenue William-David.

A new design to improve quality of life for residents

Work to modernize underground infrastructure provides Montréal with an opportunity to improve amenities and safety for pedestrians and cyclists in the district. Addition of a new array of urban furniture will make the artery more attractive so that it can become a meeting place.

Project benefits:

  • Creation of safe pedestrian routes
  • Widening of sidewalks
  • Planting of trees and other vegetation
  • Calming of vehicular traffic 

Several trees and a variety of other plants will be added after vegetated curb extensions are created. This will help green the intersections and reduce the heat island effect.

The narrowing of traffic lanes is designed to reduce car speeds, as well as improve safety for pedestrians and cyclists.
