Blue line extension – Preparatory work to begin soon in the Viau area

The Blue line extension project continues to take shape, with preparatory work beginning in the Viau/Jean-Talon area in the week of August 29. Carried out during the day, the preparations will involve relocating urban public utilities, including water pipes, sewers and underground conduits and cabling, to make way for the mass excavation, all in preparation for the new métro station’s construction. The work is expected to take ten months, with a break in winter 2023.

Mitigation measures will be in place to maintain bus service levels and lessen the impact on STM customers. Still, this is a major worksite that will involve diverting a sewer main, which will require digging to a depth of approximately 8 metres including bedrock excavation. As such, there will be some street closures on Viau boulevard and Jean-Talon Street.

Detours will be in effect for drivers, marked by appropriate road signage. Several stops for bus lines 136, 141, 188 and 372 will be closed or relocated. Residents are encouraged to check bus stop signage or the STM’s real-time information tools for full details when planning their trips, as the street closures will change depending on the phase of the work.

Access to neighbouring businesses will be maintained at all times. Safe pedestrian walkways will also be set up to facilitate movement in the area.

Plan with work phases

Staying informed
Residents are invited to visit the STM's website  for more details and updated information. There is also an electronic newsletter, to which residents can subscribe to stay informed of the latest developments.

In a call for resident participation, the STM is also in the process of forming a good neighbour committee to ensure constant contact with residents throughout the work. The committee will include representatives of citizens, groups and institutions wishing to speak for their community as the project progresses. Candidates may apply by filling out the online form. Additionally, a business roundtable has been set up for business owners affected by the Blue line extension, to keep them informed and to better understand their needs and concerns with respect to maintaining the neighbourhood’s economic health. The group will include representatives from the business community, the STM, the City of Montréal and the boroughs.
