Design and construction of 16km of double-box segmental elevated guideway. The Réseau Express Métropolitain (REM) is an under-construction fully automated light rail transit (LRT) project that will serve the major metropolitan areas in Montréal, Canada. The length of the route (67km) makes it one of the largest automated networks in the world. Overall, the LRT network will include 26 stations with three connections to the metro. The REM project involves the modernization and expansion of the Mont Royal tunnel as well as the construction with TBM of a 3.6km tunnel between Technoparc and the Montreal international airport. This project supports sustainable development and reduced greenhouse gas emissions.

Rizzani de Eccher is involved in the design and construction for the JV SNC-Lavalin-Dragados, of the elevated aerial structures of the Saint-Anne-de-Bellevue, Airport and Deux-Montagnes branches. The superstructure consists of a concrete box 2.6m high with inclined webs, 9.3m wide with a lower slab of 2m wide. The deck was designed to support two tracks, one in each direction. The catenary posts are directly attached to the deck and the rail sills are prefabricated with the segment, which facilitates the installation of the rails on site by reducing on-site operations.
