Expansion of the underground workshop and refurbishment of Viau station

Work by the City of Montréal on Pierre-de Coubertin Avenue

As of April 4, the City of Montréal will be carrying out work on Pierre-De Coubertin Avenue, between De La Salle Avenue and Viau Street.

As a result, the routes of bus lines 34 Sainte-Catherine, 125 Ontario and 136 Viau will be modified during the work, from April 4 until the fall of 2022. The map below shows the temporary bus stop locations.

A pedestrian walkway will be set up along Pierre-de Coubertin Avenue.

The metro station will remain open at all times.

Since the STM isn't in charge of this work, contact the City of Montréal's Info-travaux information line at 514-872-3777 for any questions about the work site.

Work completed at Viau station

Project summary

Viau station and its underground workshop have recently undergone major work. The station has been completely renovated and equipped with two elevators, in operation since November 2021, while the underground workshop has been expanded to double its operational capacity. All work is now complete.

The station’s new look

A great deal of work has been done, including:

  • Replacement of the waterproofing membrane of the station’s underground roof
  • Refurbishment of four staircases
  • Installation of new ceramic flooring
  • Redesign of the turnstiles to improve customer flow
  • Replacement of the curtain walls that make up the exterior walls
  • Replacement of all station lighting
  • Replacement of the butterfly doors, some of which are now motorized, for easier station access
  • Relocation of the wing gates to facilitate access in front of the ticket booth and customer flow for people with reduced mobility and families with strollers
  • Installation of new signage throughout the station

New elevators

The project was also taken as an opportunity to add elevators to Viau station, making it the 19th accessible station in the métro network.

New auxiliary structures

Two new auxiliary structures were built. The first structure contains two ventilation shafts and an emergency exit. The second structure, located behind the station, includes a new freight elevator, a natural ventilation shaft and various technical rooms.

Underground workshop expansion

The workshop located underneath Viau station - also called an attachment centre - was expanded during the project, doubling its operational capacity.

The workshop is mainly used to store various rail vehicles necessary for overnight métro tunnel and rail maintenance, and it is now connected to the new freight elevator. The expansion has also increased our capacity to transport materials and conduct different work-related activities that can often be done only at night. This will enable us to better meet the growing demands of our network’s many major worksites.

Underground workshop expansion

An underground workshop, also called an attachment centre, is located next to a station and is where rail vehicles required for night-time tunnel and track maintenance are parked. It also includes offices and a warehouse full of specialized rail parts. The métro network has three attachment centres, where approximately 25 to 30 employees are based. After the Viau attachment centre’s expansion, 12 to 15 extra employees will join the team.

A team of specialists working in the shadows is responsible for carrying out preventive and curative track maintenance, transporting construction materials and debris and providing assistance to external contractors. The team includes trackwalkers, who walk the tunnels and perform inspections during operating hours, as well as section workers and mechanics, who maintain and repair the tracks when the métro is closed. They perform work on the tracks, guide bars, running racks, clean the invert with a vacuum train and carry out relamping in the tunnels.

Expanding this infrastructure is part of the STM’s strategy to reduce its asset maintenance deficit. Our métro network is ageing and requires a lot of maintenance and renovation. Certain tasks related to these activities must be carried out exclusively at night on a very tight schedule. This constraint requires highly complex logistical planning.

The expansion will enable construction materials to be brought in and out of the Viau attachment centre, meaning they will no longer have to pass solely via the Youville attachment centre, located on the Orange line in the north of the city. This new gateway to the network from the Green line will not only increase the capacity of night-time worksites but also reduce the travel time of vehicles within the network and increase the flexibility of logistical planning. The STM will therefore be able to meet the increasing demand of its large worksites, which are increasing in size and number. This gain in versatility and performance will enable the STM to find a balance between regular network maintenance and service to external contractors.

Project planning

As for all refurbishment projects in the métro network, replacement materials are carefully chosen so that they resemble the original ones. This ensures that the look and feel of the station’s original architecture are preserved. You may find that the station’s appearance hasn’t changed much after the work, but that’s the point! Black granite, brown ceramic and concrete will remain omnipresent in the station.

The geometry, simple configuration and shallow depth of Viau station mean there are few technical challenges for installing elevators. In fact, only two elevators linking the street level to the platforms were necessary. The station’s major refurbishment was therefore a perfect time to make it universally accessible. It is also surrounded by several attractions that make it the 38th busiest station in the network, with more than 2.9 million users in 2017.

  • Viau station is one of two stations built to serve the main site of the 1976 Summer Olympic Games. Since Pie-IX station is more closely associated with the Olympic Stadium, Viau station is often referred to as “the other Olympic station.”
  • On the eastern wall of the entrance building, Jean-Paul Mousseau’s mural, Opus 74, catches the eyes of passersby. Made from turquoise and yellow ceramic tiles, the mural represents both the stadium’s tower and the Olympic flame.
  • The station’s architecture features two distinctive elements: a skylight located in the station’s centre enabling sunlight to reach the platforms and red ceramic tiles inserted between the vertical strips of split-block concrete above the platform benches.
