Alexander - Conversion of level crossings into overhead crossings

Nature of the work: 

The Réseau express métropolitain (REM) is a new automated light rail transit system. It will include 26 stations and span Greater Montréal with 67 km of tracks. The REM will gradually replace the commuter train on exo’s Deux-Montagnes line. 

For safety reasons linked to the frequency of passing REM trains, the existing level crossings will be transformed by raising the track. 

In Pierrefonds–Roxboro, the level crossings on Alexander Street and Sunnybrooke Boulevard will be converted into railway overpasses. The 11th Avenue, Gouin Boulevard West and Des Sources Boulevard level crossings will be eliminated as a result of the construction of a 1.5kilometre elevated structure.  

The following illustration shows the phases involved in constructing of the elevated structure

Impacts and mitigation measures: 

The goal of the REM project office and the NouvLR consortium is to mitigate the impact on local residents and ensure everyone’s safety by taking all appropriate measures. 

• This work will generate noise, vibration, dust and a high volume of truck traffic. 

• Appropriate mitigation measures to minimize noise and dust will be implemented based on the work in progress. 

• Long-term traffic barriers may be put in place to ensure safety at the construction zones.
