REM: Work operations underway on the Mount Royal tunnel
REM trains will travel through the Mount Royal tunnel, a century-old underground rail infrastructure located beneath Avenue McGill College.
The Mount Royal tunnel’s double vault deteriorated considerably in the McGill area due to the use of surface abrasives and the absence of a watertight membrane.
Major repairs and reinforcement work on the Mount Royal tunnel are slated to begin in mid-April 2021. The work will be carried out underground, from the inside of the tunnel, in order to minimize the impacts. However, additional obstacles will be erected on Avenue McGill College so that the work can be performed. In the northbound direction, Avenue McGill College will be fully blocked between Cathcart and Sherbrooke Ouest, and partial obstacles will be added in the southbound direction.
The REM gets active beneath the ground at McGill
Work in advance of the Réseau express métropolitain’s arrival in the McGill area will continue in 2021 and until the REM’s entry into service, expected in the fall of 2023. At the future McGill station, excavation is in the final stages and construction of the station’s structural shell (foundations and steel structure) is slated to begin in the spring.
Repair work on the Mount Royal tunnel’s double vault – which has deteriorated significantly in this area – will also begin. These work operations will span two sections, north and south of the future McGill station, and take place inside the tunnel. REM trains will travel through the Mont-Royal tunnel, a century-old underground rail infrastructure located beneath Avenue McGill College.
Major ongoing work at McGill métro station
Since March 2020, major interior and exterior work has been ongoing at McGill station. Phase one, which involved replacing the waterproofing membrane covering the station’s underground roof, is nearly complete. In mid-May, the worksite will move to De Maisonneuve and Union. Once the work is completed, McGill station customers will have access to two new elevators, a new accessible entrance building and three fully renovated entrance buildings.
