  • The Châteauguay terminus, located on boulevard Saint-Jean-Baptiste (route 132/138) is being redeveloped.

    The project, which is expected to last two years, is divided into several phases. Once the work is completed, the vehicles will have their own entrance and will no longer share the entrance with the buses. The work is carried out by exo.

    Phase 1: Sunday, August 28, 11 p.m. until mid-October (between rue Rodrigue and boulevard Industriel)

    • From Monday to Friday, dynamic lane management will provide two lanes of traffic on Saint-Jean-Baptiste Boulevard, depending on rush hour. Traffic lanes could be diverted onto the opposite roadway.
    • On Saturday and Sunday, only one lane of traffic may be available.
    • Access to businesses will be maintained at all times.
    • Local traffic could be introduced on rue Rodrigue, between boulevard Saint-Jean-Baptiste and rue Hans-Selye.

    In the event of bad weather conditions or operational constraints, the work could be postponed or extended.

    Final section of boulevard D’Anjou: preliminary work in 2023

    The portion of boulevard D’Anjou between rue Normand and the Arthur-Laberge Bridge has undergone minor repairs as the City will be replacing the sewer lines in 2024. Preliminary work will begin in 2023. To avoid repaving the same section in a short period of time and for cost reasons, only the damaged areas were repaired on a spot basis.

    The second phase of this project including the complete paving of the section will begin in spring 2024.

  • From September 19 to October 28, 2022, the Ville de Châteauguay will undertake pavement work on chemin Saint-Bernard, between rue Jack and the Kahnawake border.

    The project includes:

    • Roadway foundation replacement work;
    • Preparation of the roadsides;
    • Pavement work, marking and signage.

    During the work period, one lane of traffic will be alternated with presence of signalman. Traffic lights will be in operation at the end of the day. Slowdowns are to be expected in this sector.

    Access to chemin Saint-Bernard will be possible at all times. This work will however require a complete closure of both lanes of traffic, overnight. The closure dates will be established in October.

    Impact of the work

    For the safety of the public, the worksite safety measures may sometimes result in hindrances on roads, bicycle paths, parking lots and properties located within the power line right-of-way. These intermittent hindrances may last anywhere from ten minutes to three days.

    The work is not ever expected to lead to a power outage. If such a situation were to occur, however, the affected residents would be informed by an automated telephone messaging system.

    Mitigation measures

    A traffic plan has been established, in cooperation with the municipal authorities, to facilitate the movement of cars, cyclists and pedestrians.

    The work will be carried out during off-peak hours.

    When detours are required, appropriate signage will be in place.

    With few exceptions, access to homes will be maintained

    The work will comply with the environmental standards in effect.

  • New Water Parks

    New water parks were built in four city parks between April and June 2021. This investment of nearly $2 million will increase the number of water parks available in the territory for the enjoyment of residents in several neighbourhoods.

    Parks slated for new water parks:

    More information on this major project is forthcoming. You will soon find this information on the Past and Upcoming Major Projects.

    New Play Equipment

    Parks slated for these improvements:

    For more information about this major project, go to Past and Upcoming Major Projects.

    Naturalization of Parks

    The naturalization of our parks consists of reducing maintenance interventions to a minimum to give free rein to natural vegetation. The horticultural teams will sow new species of flowers and plant trees and shrubs all summer long to maximize the vegetation of the banks.

    Parcs slated for these measures:

  • Street resurfacing

    Resurfacing work will be carried out from June to October 2021. The schedule may change depending on the weather. The completion of this street rejuvenation plan will cost $3.5 million.

    • Cutting of mature trees within the right-of-way.
