Rehabilitation of Rothesay Avenue

Starting on August 5, 2019 the City of Saint-Lambert will be reconstructing Rothesay Avenue, as well as the portion of Arran Street between Rothesay and Rivermere avenues. The work will consist of replacing the sewers and water mains, repaving, and rebuilding the sidewalks.  

We are well aware of the inconveniences caused by such major work and the havoc they wreak in your usual routines. We therefore wish to help you prepare for them. 

Plan de détour - Rothesay


To help you get around during the reconstruction work, a detour route will be set up. We recommend following the signs that will be installed soon, indicating the route to take. This detour will be in place for the duration of the work. Local traffic will be permitted throughout the project.

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.

Planning renovations this summer?

If you are hoping to do any renovation work on your home this summer, we invite you to take into account the inconveniences caused by this major roadwork when you are planning the work.

Remember that, among other things, when excavation work is under way in front of your home to replace the pipes and rebuild the sidewalks, it will be temporarily impossible for a vehicle to access your home. This type of work usually takes ten working days. 

Take advantage of the roadwork on your street to make some home improvements 

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

► Sewer pipes and water supply mains

The City of Saint-Lambert replaces the water supply mains and sewer pipes up to your property right-of-way. 

If you think that your private water supply mains and sewer pipes, which run between your house and the property line, have a problem or are obsolete, it might be a good time to replace them.

► Driveway

If you would like to change the layout of the curb and your driveway entrance, it’s also a good time to plan this type of work. 

For more information or to plan one or more of these projects, please contact the Urban Planning, Permits and Inspection Department at 450-466-3277.


We invite you to communicate with Simon Bédard-Goulet, division head - plans and design at the Engineering Management division. You can reach him at 450 466-3889, extension 3148.

Stay informed!

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