Work on Du Poitou, D’Alsace, and Simard

In the summer of 2024, the Ville de Saint-Lambert will rebuild Du Poitou Street and a part of D'Alsace Avenue (between De Gascogne and Du Poitou streets). The work will consist of replacing the sewers and water mains, repaving, and rebuilding the sidewalks.

The city will take advantage of this opportunity to carry out resurfacing work on part of Simard Boulevard (between De Gascogne and Du Poitou streets).

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.


For the duration of the work, Du Poitou Street and D'Alsace Avenue (east of Gascogne Street) will be closed to traffic.

A pedestrian corridor (in yellow) will be maintained at all times to access the school via Béarn Avenue, Simard Boulevard or Pas-de-Calais Street.

Local traffic will be permitted throughout the construction period, and a temporary access road (in purple) will be provided when D'Alsace Avenue will be inaccessible.

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.


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.

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

You can consult the presentation made to the citizens during the meeting of December 7.

We will be holding an information session on Thursday, December 7, at 8 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.
