Rehabilitation of Riverside (phase 7)

In 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 is continuing this year, with the reconstruction of Riverside Drive between Alexandra Avenue and De Bretagne Street. All the work, including the laying of the first course of asphalt and landscaping, will be carried out over an approximately six-month period running from July to December.

Part 1 – summer

The initial zone where the work will be carried out will include Riverside Street between Alexandra and Bolton avenues. The Bolton Avenue/Riverside Street intersection will not be affected by Part 1.  

Part 2 – summer and fall

The work zone will expand from Bolton Avenue as far as De Bretagne Street. This will include the De Bretagne/Riverside intersection. This phase will involve a temporary closure of exit 78 from Highway 132. More details will be provided in due course. 

The second course of asphalt will be laid and landscaping work will be finished (if not completed in 2020) in 2021.  


To make it easier for you to get around during the work on Riverside Drive, different 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.

With some exceptions, local traffic access will be provided for residents affected by the roadwork.

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. 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.

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.

To learn more, you can view the PowerPoint presentation (in French only) that was shown at the information meeting held on February 4, 2020.
