Construction of the Rivière des Prairies railway bridge (RDP1, between Montréal and Îles Laval)

Construction activities
Starting in Spring 2020 From 7 a.m. to 7 p.m.* On weekdays and weekends
North Shore

Nature of the work

Construction work on the new railway bridge adjacent to the existing one will resume this spring in order to allow the REM to run above the Rivière des Prairies between Montréal and Îles Laval.

The work scheduled to begin in the spring includes the construction of the bridge approach abutment on the south shore of the river, followed by the assembly of the bridge deck, which will consist of prefabricated steel beams. The incremental launching method will be used to install these beams. Lifting equipment will be positioned on concrete blocks on the south shore of the river, from which the beams will be launched onto the foundations (piles and pierheads). Each subsequent beam will push the previous one until the installation is complete.
