Getting on track: Urban transit projects roar to life, creating opportunity for Canada’s construction sector

Working in tandem along a stretch of highway in Montreal, a pair of launching gantry cranes hoist 50-ton concrete segments into the air off flatbeds below. The gantries slide the prefabricated segments into place, steadily forming a single 30-metre span over the course of two days.
The three-year journey has just started for the cranes, affectionately nicknamed Anne and Marie. With the help of construction crews, the massive yellow beams are building more than a dozen kilometres of elevated track on which the Réseau express métropolitain’s (REM) rail cars will eventually run.
