Construction of the Pie-IX station

Texte important

September 25, 2024 - Start of work – Pie-IX

We are kicking things off for the excavation at the site of the future Pie-IX* station. The work will require some street closures and changes in commuter routes. For details, see under Impact on customer trips and Impact on local residents sections.

Construction site summary

As part of the Blue line project, this worksite involves building a new accessible métro station with two entrance buildings and a bus terminal. The entire extension is expected to be commissioned in 2031.

Please note that the station name is tentative.

A direct link to the Pie-IX Boulevard bus rapid transit (BRT) service

The pedestrian tunnel, which will link the future Blue line extension Pie-IX métro station to the Pie-IX BRT, is currently under construction, as part of the integrated Pie-IX BRT project.

September 2024

September 25, 2024 - Start of work – Pie-IX

We are kicking things off for the excavation at the site of the future Pie-IX* station. The work will require some street closures and changes in commuter routes. For details, see under Impact on customer trips and Impact on local residents sections.

Partial dismantling of Le Boulevard shopping centre

Dismantling continues for a portion of Le Boulevard shopping centre (orange area). We’ll be removing the unoccupied portion to ensure that the upcoming Blue line project worksite doesn’t get in the way of normal shopping centre activities.

Good to know:

  • Stores will stay open during the work.
  • Work will take place from Monday to Friday.
  • The partial dismantling may cause noise, vibrations and dust.
  • Mitigation measures will be in place to reduce disturbances.

Next steps

  • The west side of the Centre Le Boulevard building is being demolished.
  • On September 25, 2024, excavation work will start and Jean-Talon street will be closed to traffic.

Impact on customer trips

Once the contractor is deployed, stops for lines 141, 188 and 372 between Pie-IX and Provencher will be relocated. Westbound stops will be moved to Everett, and eastbound stops will be moved to Bélanger.

Impact on local residents

Once the contractor is deployed, Jean-Talon Street will be closed to traffic while the site is cordoned off, and the work will begin. The first few months will involve relocating urban public utilities (water pipes, sewers, and underground cabling) so that the mass excavation can begin.

This is a key worksite for the Blue line extension, as it is where the tunnel boring machine will begin digging the métro tunnel and where all the excavated material will be removed.

Good to know :

  • Access to homes and businesses will be maintained at all times.
  • Signage will be posted to direct pedestrians, cyclists and drivers.
  • Worksite trucks will be circulating on Pie-IX, Jean-Talon and Provencher.
  • To reduce the negative impact on local residents, we will implement specific mitigation measures. This will include installing noise walls around the worksite perimeter.

IMPACT OF WORK

  • Jean-Talon will be completely closed to traffic between Pie-IX and 24th Avenue.
  • 23rd Avenue will become a dead end and be set up for two-way traffic. This will require some parking spaces to be removed.
  • 24th Avenue will be blocked for a few days while the site is being set up, but will then be open throughout the work.
  • Roads will remain open to local traffic between the worksites on Jean-Talon.
  • There will be a reserved lane running eastbound on Bélanger, between 19th Avenue and Provencher. Stay alert and read all posted signage before parking.

  • The north sidewalk on Jean-Talon will remain open to allow east-west foot traffic.
  • The south sidewalk will be blocked by the worksite.
  • The east sidewalk on Pie-IX will be closed for a few weeks during the initial phase. It will then be reopened for the rest of the project.
  • Flaggers will be present at worksite entrances and exits for pedestrian safety.
  • Stay alert, only cross the street at traffic lights and crosswalks, and follow all instructions from the worksite crews.

Partial dismantling of Le Boulevard shopping centre

We will continue the dismantling of a section of Le Boulevard shopping centre (orange area). We’ll be removing the unoccupied portion to ensure that the Blue line project worksite doesn’t get in the way of normal shopping centre activities. The excavation site of the new métro station is identified by the blue area.

Join your local good neighbour committee!

Do you live near the future Pie-IX station or Provencher auxiliary building and want to have your say in how the Pie-IX 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.

Questions and answers

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 Blueline 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.

In 2020 and 2021, two archeological potential studies were conducted at the sites of several future structures. This is standard procedure whenever we break ground on a project of this scale that requires excavation. Three future métro stations were identified for targeted interventions, at Pie-IX, Viau and Saint-Michel. These sites were chosen because they are located along the watershed of the Ruisseau du Pont à l’Avoine, a now-dried stream that existed until the 1950s. It flowed south to join the Ruisseau Molson and into the St. Lawrence.

  • The sites of the future métro stations at Pie-IX and Viau will be studied as they are likely to show signs of former Indigenous occupation.
  • The site of the future Saint-Michel power station, located beside the métro station of the same name, is potentially significant to European Quebec history, since it was occupied more recently in the early 20th century. A delivery company occupied the space until the 1960s, when the building was destroyed by fire.

How are the digs conducted?

An expert archeological firm has been hired to conduct the digs. After analyzing the sites and leading archeological potential studies, the archeologists will choose locations for inventory trenches. The trenches will be roughly one metre deep and will allow the researchers to physically evaluate the site’s potential.

What do you do if there is a find?

If anything is found, the trench where it is discovered will be enlarged, and additional probes will be done to evaluate its archeological features. An inventory is also conducted as needed.

Have you ever found any historical artifacts?

At the site of the future Pie-IX (working name) métro station, archeologists unearthed a stone wall and a wooden beam. Although these vestiges show that the site was occupied at the beginning of the last century, they were not of significant heritage value. An archaeological inventory was carried out to document the precise location of the ruins. The inventory included a qualitative and quantitative identification, ensuring the protection and safeguarding of the vestiges’ data.

Yes, the shopping centre will be able to remain in operation during the expected construction period of the new Pie-IX station. However, it will be partially deconstructed to prevent any interference with worksite or shopping centre operations.

The STM acquired the building on December 1, 2021, following the expropriation process started earlier in the project timeline.

The property will be managed by STM subsidiary Transgesco. A recognized company specializing in this area has also been mandated to manage shopping centre operations.
