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 and Airport

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 complete closure of the Cornwall bridge will take place in the night on May 19 to 20.

Impacts 

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.
  • A police presence is planned during the first week of the obstruction to ensure traffic safety. Close monitoring will be carried out on the train to make the necessary adjustments.
  • 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.
