Construction of the elevated structure ar the Airport junction

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.

And to ensure the transition between the elevated structure and the ground-level route, construction of reinforced earth walls will be initiated. These transition ramps will be built using reinforced earth to support the slope fill and the weight of the railway infrastructure. The ramp will be located near the Highway 13 junction.

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.
