Rehabilitation of a portion of Green Street

Rehabilitation of a portion of Green Street

In the summer of 2024, the Ville de Saint-Lambert will rebuild part of Green Street (between Notre-Dame and Oak avenues). The work will consist of replacing the sewers and water mains, repaving, and rebuilding the sidewalks. The City will take advantage of this work to decontaminate and rebuild the library parking lot.

All work, including the first layer of paving, is expected to last until the end of summer 2024. The second layer of paving will be laid in the summer of 2025.

We are conscious of the inconveniences caused by such a major project and how they will disrupt your daily life. We would therefore like to help you prepare for the work.


  1. Week of April 15: Gradual mobilization of contractor (excavation, demolition, temporary aqueduct, etc.)
  2. Week of April 22: Sewer and aqueduct work begins on the section between Mercille and Oak avenues.
  3. End of June (after school ends): Sewer and aqueduct work begins on the section between Mercille and Notre-Dame avenues.
  4. Summer: Sidewalks, paving and surface rehabilitation
  5. Late summer: Completion of work


Once work begins, Green Street will be closed between Mercille and Oak avenues.

At the end of the school year, Green Street will be closed between Notre-Dame and Oak avenues. The detour will then take place via Victoria Avenue.

Local traffic will be permitted throughout the work.

The reconstruction of a street is a complex operation involving several companies, and it disrupts people’s lives. We invite you to consult the Practical information during roadwork page, which will offer practical tips to ensure your daily routine remains as unaffected as possible.

If you wish to carry out renovation work on your home this summer, we invite you to consider the inconveniences caused by this major roadwork when planning your project. Remember that, among other things, when excavation work is underway to replace the pipes and rebuild the sidewalks in front of your home, it will be temporarily impossible to access your home with a vehicle. This type of work usually takes 10 working days.

During this roadwork, the entire street will be rebuilt, including replacing the water supply mains, sewer pipes, roadway, and sidewalks. You might want to undertake certain projects, which will be easier to do at this time, such as:

Sewer pipes and water supply mains

The Ville de Saint-Lambert will replace the water supply mains and sewer pipes up to the right-of-way of your property.

If you think there is a problem with your private water supply mains or the sewer pipes that run between your home and the property line, or that they might be obsolete, this would be a good time to replace them after the end of the rehabilitation works.


If you would like to change the configuration of your curb and driveway entrance, this would also be a good time to schedule such work. You must submit your demand before April 19, 2024.

The information on this page will be continually updated. We invite you to check it regularly for progress reports on the work.

Repair work on Green Street will begin this Tuesday, April 16. For the first phase of work, the street will be closed between Mercille and Oak avenues. On-street parking will no longer be possible on this section of the street. In addition, the parking spaces reserved for the library on Mercille Avenue will be partly occupied by the construction trailer.

Citizens who need to get to St. Lambert Elementary or the library will have to plan to park on the streets around the worksite.

Whenever possible, we encourage you to consider walking or cycling to get to the sector.

We also ask you to respect the detour route and signage at all times.

You can consult the presentation made to the citizens during the meeting of October 25.

We will be holding an information session on Wednesday, October 25, at 7 p.m., at the multi-purpose centre (81, Hooper Street) to present this project to the public. You can also watch the meeting live on our YouTube page.

During this information session, we will explain the key aspects of the project and present the projected plans and timeline. We will also give you some practical tips to ensure that your daily routine remains manageable and endeavour to answer any questions you may have
