The REM’s elevated structure on the West Island allows for the construction of a linear route, limiting the footprint and the impact of the construction work.
The height of a column varies according to its location on the route, with a minimum clearance of 5.3 meters (Ministère des Transports standard) beneath the deck to ensure traffic safety.
REM construction work will continue throughout the winter of 2021:
Construction of the four stations on the Anse-à-l'Orme branch
Installation of the deck on the elevated structure using the launching gantries and installation of the new railway infrastructure (rails, electrical system, etc.)
REM crossing over A40
Nature of the work:
Beginning August 2, traffic pattern disruptions are planned on Highway 40 (A40) at Saint-Jean Boulevard within the framework of REM elevated structure construction on the West Island.

This “major crossing” will be carried out in several phases over a period of approximately one month (from August 2 to September 10).

Impacts and mitigation measures:
Just as on any construction site, the work may cause noise, dust, vibrations and require trucking.
Mitigation measures will be implemented as needed to mitigate impacts at the source (temporary noise barriers, low-noise equipment, white noise vehicles).
Monitoring by environmental experts will take place throughout the work.
*Dates subject to change. Activities may be required before or after the scheduled times.
