Construction of the elevated structure along the Doney Spur

Construction activities
Beginning summer 2019 From 6:30 a.m. to 7 p.m.*, 7 days a week, depending on work progress
Montréal (West Island)

Nature of the work

The foundations of the elevated structure, including the caissons, columns and pierheads, have now been completed in certain sectors, so construction of the deck of the REM’s elevated structure can now begin using launching gantries.

Prefabricated segments will be assembled one after the other to form the deck on which the REM’s rail cars will run.

Impacts and mitigation measures

Road traffic is permitted beneath the equipment thanks to engineer certification that the prefabricated segments are securely anchored. Nonetheless, full and partial closures will be implemented when the prefabricated segments are delivered, raised and assembled.

Just as for any construction site, the work will generate noise, vibrations, dust, heavy truck traffic and traffic disruptions. Mitigation measures will be implemented to prevent or minimize the impact on surrounding residents and ensure everyone’s safety.


Elevated structure

The REM’s elevated structure on the West Island allows for construction of a linear route, limiting the footprint and the impact of the construction work. 

Column height varies depending on a column’s location on the route. There will be a minimum clearance of 5.3 metres (Ministère des Transports standard) below the deck to ensure passage of vehicules.
