In order to provide an efficient alternative solution for users of the Deux-Montagnes suburban train line during construction work on the Réseau express métropolitain (REM), CIMA+ designed bus priority measures (BPM) for the segment between the Sainte-Dorothée station and the Lachapelle Bridge. These measures included widening of the roadway to add a reserved lane and allow buses to travel on the shoulder, along with traffic signal pre-emption measures on avenue des Bois and boulevard Chomedey. The project was completed in record time, before discontinuation of the suburban train service.
