Rehabilitation of Riverside (phase 6)

Chantier RiversideIn 2012, the City began a major project to rehabilitate Riverside Drive, the longest artery in Saint-Lambert. The work is being spread over several years. To learn more about this large-scale project, consult the Riverside Drive project description page.

Work will continue this spring, with the reconstruction of Riverside Drive between D’Anjou Avenue and Brossard’s city limits. This work includes the Du Rhône Avenue and the portion of Simard Boulevard from the De Gasgogne Street to the junctions on Autoroute 132. This phase of the work, including the first course of asphalt, should be carried out over a period of six months, from June to November. 

Phase 1: summer

The area for this phase of the work will include Riverside Drive between Hickson and Alexandra avenues. The intersection of Alexandra Avenue and Riverside Drive will not be affected during phase 1. 

Phase 2: fall

Work will continue between Hickson and Alexandra avenues, but will extend to the intersection of Alexandra Avenue and Riverside Drive. The work was divided into two phases to ensure that the intersection is closed to traffic for the shortest time possible.

The starting date for the work will be confirmed in the spring once the contract has been awarded to the contractor who will carry out the work. 

The second course of asphalt will be laid and the landscaping done in spring 2019.


To make it easier for you to get around during the work on Riverside Drive, two detour routes have been planned according to the progress of the work. We recommend following the signs that will be posted soon, as they will indicate the best detour for vehicles.

Detour routes

Neighbourhood residents

The reconstruction of a street is a complex operation involving many companies, and it creates a great deal of disruption to people’s routines. The page Practical information on roadworks will offer you practical tips to ensure your daily routine continues as smoothly as possible.


Many of the Réseau de transport de Longueuil (RTL) buses travel along the entire length or a section of Riverside Drive. For the duration of the work, alternate bus routes will be set up for lines 13, 37 and 55. You can consult the RTL's website for more details. 

The RTL will also install temporary signs informing users of any changes to the usual Riverside Drive bus routes. 

For more information, you can call the RTL’s Customer Service Department at 450-463-0131 from Monday to Friday between 7 a.m. and 8 p.m., as well as on weekends and holidays between 8:30 a.m. and 4:30 p.m.

Nouvelle conduite pluviale à l'aide d'une technique sans tranchée

Trenchless pipe installation

The most important aspect of the rehabilitation of this portion of Riverside Drive will be the installation of a new 1800 mm-diameter stormwater drainage pipe using a trenchless method. This pipe will be laid at a depth of approximately 9 metres below ground and will pass under overpasses belonging to both the Ministère des Transports, de la Mobilité durable et de l’Électrification des transports (MTMDET) and CN. 

This major project will make it possible in the coming years to proceed with the separation of the combined sewer systems and better serve the sector located between highway 112 (Sir-Wilfrid-Laurier Boulevard) and the Country Club of Montreal golf course.

To learn more, you can view the PowerPoint presentation (in French only) that was shown at the information meeting held on February 8. 

Cycling overpass

During the project, the City of Saint-Lambert will ensure cyclists who use the overpass have access to it despite its proximity to the worksite. 

However, there will be a period of several weeks when major work will be carried out around the base of the overpass. During this time, access to the overpass will be completely closed for safety reasons. We are aware of the inconvenience this may cause and will do our best to reopen it as soon as possible. The closure dates will be announced soon. 

Pedestrian safety  

During the reconstruction work, the City of Saint-Lambert will set up an enhanced surveillance system. However, we urge parents to inform their children of the potential dangers associated with such major work and to watch out for the safety of the children in their neighbourhood.

Questions about the worksite?

We are well aware of the inconveniences caused by such large-scale work. We thank you in advance for your cooperation. If you have any questions about the project, please contact Vasco Morgado, a municipal engineering technician with the City of Saint-Lambert’s Engineering Department, at or at 514 290-1424.  

Stay informed!

The information you’ll find in this section of the website will be continually updated. We invite you to check this page often for reports on the progress of work.


2018-02-02 - Information evening
In the spring, the City of Saint-Lambert will begin phase 6 of the work on Riverside Drive, the longest artery in the municipality. This phase of the work will involve rebuilding the section of Riverside Drive between Alexandra and Hickson avenues.

In preparation for this project, the municipal team is inviting you to an information evening on Thursday, February 8 at 7 p.m. at City Hall. The goal of the evening is to explain in detail the scope of the work that will be done and to prepare residents for the impact the work will have on their daily life. They will also be able to ask their questions to the main project managers.
