Public information session - Langelier sector
An information session was held on October 10, 2024, to inform residents about the start of work to build the new métro station in the Langelier area and the resulting full closure of Jean-Talon Street.
Impact on customer trips
Due to the start of construction on the new Pie-IX, Viau and Langelier métro stations in fall 2024, buses 141 and 372 have been rerouted onto Bélanger Street between 19th Avenue and Des Halles Street since October 28. A reserved lane has been set up on Bélanger to facilitate mobility during the work.

Impact on bus service - Langelier sector
Bus stops for lines 141 and 372 on Jean‑Talon Street have been relocated on Bélanger Street since October 28, 2024.
The stops for line 33 northbound on Langelier Street at the corners of Dumesnil and Jean‑Talon have also been canceled since that date due to construction work on the new Langelier métro station.
Impact on local residents
January 2025 : installation of retaining walls around the excavation zone
Work will resume at the Langelier site on January 6. Crews will focus on building retaining walls around the excavation zone for the new métro station. These will keep the soil stable during the mass excavation.
The retaining walls will be anchored by piles, which will be installed starting in the first week of January. The process will take around four weeks.
A working method that reduces the impact
During this phase, some worksite noise is unavoidable. However, to keep it to a minimum, we’ll be installing the piles by drilling rather than driving whenever possible. Pile drilling uses specialized drills to dig into the ground to the correct depth. Steel columns are then installed in the shafts and anchored with poured concrete. This method is quieter for local residents compared to pile driving.
Although most of the piles will be drilled, some pile driving may prove necessary in certain situations. Rest assured that measures are in place to control the impact of our work. These include noise walls around the worksite perimeter to dampen the sound.
Excavation work started October 28, 2024. Part of Jean‑Talon has had to be closed to traffic so that crews can excavate the site of the new Lacordaire station.
Pedestrian traffic
- An east-west walkway has been set up on Jean‑Talon to allow pedestrians to walk around the worksite.
- The eastern sidewalk of Langelier is closed along the worksite, but the western sidewalk is still open.
- Pedestrians can reach Carrefour Langelier shopping mall from the east via a walkway on Jean‑Talon.
- Stay alert, only cross the street at traffic lights and crosswalks, and follow all instructions from worksite crews.
Car traffic
- A part of Jean-Talon Street is fully closed to traffic east of the intersection with Langelier Boulevard.
- Jean-Talon remains open to traffic both east and west of the worksite.
- On Langelier, two northbound lanes are closed, leaving one lane open in the worksite area.
Good to know
- Access to businesses and residences will be maintained at all times.
- Signage is in place to direct pedestrians, cyclists and drivers.
- The worksite trucks will use Langelier, Jean-Talon and Métropolitain
- Specific mitigation measures are in place to reduce the impact on local residents, including noise walls around the worksite perimeter.
Join your local good neighbour committee!
Do you live near the future Langelier station and want to have your say in how the Blue line project worksite will fit into your neighbourhood this fall?
A good neighbour committee will be set up in the coming weeks as a space for dialogue between the STM and the local community. We’re currently looking for people who live in the area to join the committee and represent local residents at a few meetings per year.
The committee’s purpose is to:
- Provide information and outline the different phases of the project.
- Start a dialogue between residents and project representatives that will continue throughout the work.
- Discuss how the impact of the work will be managed so that resident members can share this information with their local community.
- Understand the concerns residents have about the work and find solutions together.
- Allow local residents to make suggestions on specific topics chosen by the project office.

Learn more about the project
In the coming months, we’ll be starting excavation work to make way for new infrastructure for the Blue line project.
The excavation method will vary depending on the type of work being done. The surface excavation work will involve controlled microblasting, whereas most of the excavation for the underground tunnel will be done using a tunnel boring machine, or TBM. At both types of worksites, there will also be some mechanical excavation. The vibrations produced by the different excavation methods will be measured on an ongoing basis using seismographs. These devices will be installed at various points throughout the excavation zones and will be used to continuously monitor the vibration levels and make sure they fall within legal limits.
Essential preventive measures
To prepare for upcoming excavation work, the STM has tasked ABS with inspecting buildings that meet at least one of the following criteria:
- Located within 75 metres of any surface-level excavation work
- Located within 30 metres of the tunnel axis
The inspections will serve to compile an inventory of the structures surrounding the worksites for the Blue line project. The findings of the inspections will also be used to establish the maximum vibration levels for each site. Although these inspections are a precautionary measure, they are essential in the unlikely event that the work causes any damage.
As a further precaution, any building within 100 metres of a worksite where there will be microblasting will receive a carbon monoxide detector a few weeks before the excavation work starts.
Each building inspection lasts approximately 15 to 30 minutes. Photos are taken of the building interior and exterior. The photos are mostly close-ups of the foundations, walls, ceilings, and floors and serve to document the building’s condition prior to the start of the excavation work.
The pre-construction inspection is a common precautionary measure for major construction sites. It protects you in the unlikely event that your property suffers any damage during work on the Blue line project.
Controlled microblasting is used on several major STM worksites, depending on the type of rock to be excavated. To learn more, watch the video in the FAQ section of our Blue line project page.
In the fall of 2024 and 2025, urban forestry work will take place around the Blue line project worksites. Trees that interfere with the construction sites will be protected, replanted, or cut down. Our team of forest engineers, landscape architects, urban planners, and sustainable development experts has carefully planned these interventions to preserve as many trees as possible.
The goal is to replant the trees wherever possible. Soverdi, the not-for-profit organization overseeing the replanting process, will monitor and care for the trees after they are transplanted to ensure their survival. Trees that can’t be replanted due to their size or condition will be recycled into wood chips, firewood or compost depending on the quality of the wood. The health and species of the trees will also help determine which ones need to be cut down, based on whether they are diseased, subject to borer infestations, or invasive, among other factors.
Ultimately, Blue line project sites will be revegetated and several hundred new trees planted, for a stronger, healthier canopy. For every tree replanted or cut down, we will plant more than two in their place.
The work involved relocating urban public utilities, giving us free rein to begin the massive excavation that will be needed to build the new métro station. The utilities that needed to be relocated included water pipes, sewers and underground conduits and cabling.
Before the preparatory work, the project team prepared informative video clips. Watch these clips to learn more about the project:
Description of the preparatory work in the Langelier area (in French).
Yes. When we conduct the mass excavation to build the new métro station entrance building, the land will be decontaminated in compliance with current environmental standards.
