Montreal’s REM bores tunnel under sensitive airport lands It’s like an underground submarine, boring beneath the Earth’s surface. In this case it was the Robbins Earth Pressure Balance custom designed Tunnel Boring Machine, which has now completed one of the most delicate construction segments for Montreal’s new Réseau express métropolitain (REM) 67 kilometre light rail network. The almost two-year drilling of 2.5 kilometres under the delicate soft soil took place in the so-called West Island Technoparc wetlands and the runways of the city’s Trudeau International Airport. It’s the only section of the surface and elevated REM that had to be bored underground, so as not to disrupt the natural ecology as well as the massive airport infrastructure leading to a station in the bowels of the airport, due to open in 2025.
