Hydro-Québec property, located between Avenue Dollard and 90e Avenue.

Schedule

  • Mid-November to end of November 2022 (approximately 3 days) : preparatory works
  • January to summer 2023 : construction of a main drinking water line

Work details

  • Preparatory works : exploratory excavations
  • Construction of a main drinking water line : the method used will be the open-trench excavation method. This excavation method digs from the surface, creating a trench in which new pipes are laid. At the end of work, the site will be returned to its previous condition.

  • Construction of a valve chamber and connection of the chamber to the existing drinking water network on the 90e Avenue, between Rue Airlie and Boulevard Newman, at the Hydro-Québec property. 

  • Construction of the main water line and valve chambers on the Hydro-Québec property. The excavation will be located within the site right-of-way and will run behind the businesses backing onto the property.

  • Construction of the main water line and connection to the existing network at the corner of the Hydro-Québec property and Avenue Dollard.

Getting around during the project

  • 90e Avenue: Partial and complete barriers are to be expected between Rue Airlie and Rue Newman during construction of the valve chamber and connection of the new line to the drinking water network. Detour routes are planned. 

  • Avenue Dollard: Narrowing of the westbound traffic lane is to be expected between Rue Salley and Rue John-F.-Kennedy during work to connect the new line to the drinking water network.

Pedestrian
