Worksite update - November 2022

Temporary closure of Greene Avenue

On November 9, Greene Avenue will be closed for the day between Delisle and Saint-Jacques as there will be a crane on this street. The crane will be used to deliver equipment to the Lionel-Groulx rectifier station located southwest of Rollande-Danis-Pelletier Park. Repairs at the rectifier station are being carried out at the same time as work on the nearby Lionel-Groulx power station.

Since traffic on Greene is currently limited to buses and the trucks needed for the work at the Lionel-Groulx power station, there will be no changes to traffic in the area. Bus service will not be affected either since stops will not be moved.

Worksite update

Work at the Lionel-Groulx power station is making good progress and the construction of the new building is almost complete. The work is now mainly done inside the building, including the installation of various electrical and mechanical equipment. The project is still expected to be completed in the fall of 2023. Work at the Lionel-Groulx rectifier station should be finished in February 2023.

Impact on customer trips

 

The station will remain open at all times during the work.

Greene Avenue is closed to traffic between Delisle and Saint-Jacques streets during this phase of the project, except for vehicles required for the construction site and for buses. That said, it is preferable that the buses do not stop in the area near the worksite for safety and traffic flow reasons given the prevalence of construction-related vehicles and trucks there. The bus stops on Greene Street are therefore relocated to adjacent streets:

  • The 211 Bord-du-Lac and 425 Express Anse-à-l’Orme stops will be relocated onto Saint-Jacques Street just west of Greene Street.
  • The 405 Express Bord-du-Lac stop will be merged with the 78 Laurendeau stop on Saint-Jacques Street east of Greene Street.
  • The 485 Express Antoine-Faucon stop will be relocated onto Saint-Jacques Street just east of Atwater Avenue.
  • The 71 Du Centre stop will be relocated onto Delisle Street just east of Atwater Avenue.

Getting off the bus

To stay on schedule as much as possible, buses will let riders off on Saint-Jacques Street west of Greene Street. Riders will then have to walk about 200 metres to reach the Lionel-Groulx entrance building.

Riders cannot be let off closer to the station because buses would have to make a turn to get back to their pickup stops that would take several minutes, potentially more with traffic. This would result in late departures.

While Greene Avenue may now appear to be more accessible, for safety reasons it is important to avoid increasing traffic on this stretch, especially because of the prevalence of construction-related vehicles and trucks there.

Impact on local residents

Pedestrians and bikes

The bike path that runs through the park has been relocated since the area west of Greene Avenue is a construction site. The bike path is diverted on Delisle Street, between Atwater Avenue and Rose-de-Lima Street, until the work is completed. 


Vehicle and bus traffic will stay the same on Delisle Street and we expect an average of four trucks per hour during the work.

We will have to block about five parking spaces on Saint-Jacques Street during the work.

Refurbishment of the Lionel-Groulx rectifier station

Repair work is underway at the Lionel-Groulx rectifier station, located southwest of Rollande-Danis-Pelletier Park.

Construction is carried out in a limited area of the park, and takes place mainly inside the building. As a result, there will be little impact on local residents.

We will need to use a crane for a few days on two occasions, between now and the end of the work at the Lionel-Groulx rectifier station in January 2023. This could partially impact traffic on Greene. Please note that traffic on this street is currently limited to buses and the trucks needed for the work at the Lionel-Groulx electrical substation.

Work at the Lionel-Groulx rectifier station will take place from Monday to Friday starting at 7 a.m., in accordance with municipal by-laws.

This refurbishment is needed to maintain the métro’s electrical power supply system, as the equipment currently in use has reached the end of its service life.

Refurbishing an electrical substation presents a unique challenge as the métro’s power supply cannot be cut off during the work. The equipment must remain in use to ensure uninterrupted métro service.

An electrical substation houses the equipment needed to supply power to the métro network. There are several electrical substations located across the STM métro network.

The project will mainly consist of constructing a new building where the Lionel-Groulx garage is currently located, between Greene Avenue and Rose-de-Lima Street. This garage houses the current electrical substation. The new building will house updated electrical equipment and a garage where maintenance vehicles will be stored.

No. The electrical equipment’s fans are equipped with powerful noise suppressors. Once the station is operational, the noise it emits will comply with municipal by-laws and will be no louder than current levels. In fact, it will be lower than normal conversation or the area’s usual ambient noise level.

This repair work aims to ensure the viability of the rectifier station and the reliability of the métro service. The work area is located southwest of Rollande-Danis-Pelletier Park.

What is a rectifier station?

A rectifier station holds equipment that is necessary to supply electrical power to the tracks in the métro. There are several rectifier stations spread out throughout the STM’s métro network.

We will also be replacing the waterproofing membrane that protects the station’s underground roof from leaks. This worksite will cover an area from the station’s main entrance building to the garage, located west of Greene Avenue.

Some trees located within the worksite will be replanted elsewhere in the park, while others will have to be cut down. During project analysis, a comprehensive survey and forest engineer’s report were completed. Plans to compensate for canopy loss have been made in accordance with this report and following consultation with a City of Montréal agronomist. When the work is completed, we will have planted more trees than will have been cut down, improving the park’s canopy. Landscaping will also be done on site.

In the interest of improving your trips, we need to carry out major repairs to the staircases of Lionel-Groulx station. This work will ensure the watertightness of the entrance building and the stairs to prevent damage from water infiltrations.

This work is needed to replace the entrance building slab and the staircase steps, which have reached the end of their useful life. To do this, we have to demolish the existing staircases, rebuild them, and then refurbish the granite surfaces.

The steps for this project are:

  • Replace granite steps, landings and floor finishes.
  • Improve the watertightness of structures.
  • Install a waterproofing membrane and expand the trench drain.
  • Replace the escalator frames.
