Cornwall bridge reconstruction and dalle park construction

Road  | Major
From May 2020 Mainly during the day between 7 a.m. and 7 p.m.
Centre of Montréal

Nature of the work:

The closure of the Deux-Montagnes line as of May 11th, 2020 presents a unique opportunity to access the rail line in order to demolish and rebuild the Cornwall bridge to current standards. NouvLR will also proceed with the construction of a dalle park, an infrastructure that will link the Graham/Laird and Cornwall road bridges and on which the Town of Mount Royal will then build a public square to facilitate access on both sides of the railway line.

The following map shows the work location and traffic obstructions:


The goal of the REM project office and the NouvLR consortium is to mitigate the impact on surrounding residents and ensure everyone’s safety by taking all appropriate measures.

  • This work will generate noise, vibrations, dust and truck traffic. Long-term traffic barriers will be put in place to minimize construction traffic and secure the construction zones.
  • The traffic situation is likely to be challenging due to increased construction work in the area. Commuters are invited to avoid the area when possible.
