Blue line extension – Upcoming preparatory work in the Langelier area

Preparatory work for the Blue line extension will begin in the Langelier/Jean-Talon area during the week of August 7, 2023. The work will involve relocating urban public utilities for the massive excavation that will be needed to build the new métro station. The utilities that need to be relocated include water pipes, sewers, and underground conduits and cabling.

The work will be carried out in phases to reduce the impact on travel in the area. Work will be done during the day, but streets will remain closed overnight. Detours will be in effect, marked by appropriate road signage. Several bus stops will be closed or relocated. Depending on the phase, this will mainly affect lines 33, 141 and 372. Signage will be put up at the affected stops, and a range of real-time information tools will be available to inform users of detours in effect and help them plan their trips. Access to neighbouring businesses will be maintained at all times.

Preparatory work: 1 week
  • Jean-Talon Street: One lane open in each direction
