REM: Demolition of Cornwall bridge and obstructions on Jean-Talon Street

Montréal Published on

Two weekends of major work in the area 

Major work is to be watched over the next two weekends in the Town of Mount Royal sector as part of the construction of the Réseau express métropolitain (REM).

  • First, due to a very advanced state of deterioration, the Cornwall bridge will be completely demolished this weekend, June 13 and 14, 2020. The bridge will then be rebuilt to ensure its integrity for the next 100 years. It will be possible to watch the work live on the REM website. 
  • In addition, a complete closure of Jean-Talon Street is scheduled from June 19 at 11 p.m. to June 22 at 5 a.m. to reconfigure the lanes to allow for the complete reconstruction of the bridge’s north deck. Traffic will then be redirected to the south side of Jean-Talon Street West with one lane open in each direction. 

Cornwall bridge: A historic moment to watch live!

The history of the Cornwall bridge is closely linked to the establishment of the Town of Mount Royal, whose urban planning was developed around the railway line that crosses Mount Royal. The construction of this bridge dates back more than 100 years, to the time when the Deux-Montagnes line was commissioned. A page of history will be turned this weekend. It is also the beginning of a major transformation for the sector with the arrival of automated light rail technology and the development of a public square that will unite the Town of Mount Royal's town centre. 

Note that this work may take place because of the complete closure of the Deux-Montagnes line. Three power shovels will work on both sides of the bridge and on the rails to completely demolish the bridge. Debris will be transported within the railway right-of-way to limit transit through the downtown area. Due to the nature of the work, there may be a higher level of noise, dust and vibration in the area, in spite of the implementation of mitigation measures. 

Watch this major work live throughout the weekend!

Jean-Talon bridge completely closed on June 20 and 21

Work on the complete reconstruction of the Jean-Talon bridge, an obsolete infrastructure deemed critical by the City of Montréal, is entering a new phase: the demolition and full reconstruction of the north deck.  

The reconfiguration of the lanes required to complete this new phase of the work will require a complete closure on the weekend of June 19 to 22 for a period of 48 to 72 hours, between Dieppe Avenue and Aberdare Road. Work will begin the night of June 19 to June 20, at 11 p.m. Drivers are encouraged to plan their travel during this period.

Starting June 22 at 5:00 a.m., traffic will be redirected to the south side of Jean-Talon Street West with one lane open in each direction. This new configuration will allow demolition work on the north deck to be carried out during the summer.  Another complete weekend closure will be required during the summer in order to continue the reconstruction of the bridge, which will continue through 2021. Citizens will be kept informed through various Works info notices posted here. It should be noted that the reconstruction work on the Jean-Talon bridge will take two years, due to the phasing required for the work.
