Quebec’s provincial government announced on Tuesday that it will redesign a stretch of Highway 10 between Brossard and Carignan to include dedicated lanes for buses and high‑occupancy vehicles. The plan also calls for a comprehensive upgrade of the aging roadway infrastructure along the corridor. Officials said the changes are intended to make it easier for South Shore commuters to reach the REM rapid‑transit system.

Highway 10 serves as a primary artery for residents traveling between Montreal’s South Shore municipalities and the city core. By adding separate lanes for public transit and carpool traffic, the province aims to increase the capacity of the route without expanding the total number of lanes. The dedicated lanes are expected to encourage more drivers to share rides and to shift more passengers onto the bus network that connects with REM stations.

The REM light‑rail line already provides rapid service to several points on the South Shore, and the new lane configuration is designed to improve the link between road‑based commuters and the rail system. Transportation officials indicated that the reserved lanes will be integrated with existing interchanges and that the broader infrastructure renewal will address pavement wear, drainage, and safety features that have deteriorated over time.

The announcement comes as part of a wider provincial effort to modernize key commuter routes and to support sustainable travel options. While the project remains in the planning stage, the government will move forward with detailed design work and environmental assessments before construction begins.

The initiative reflects the province’s focus on improving mobility for South Shore residents, reducing congestion on a heavily used highway, and strengthening the overall connectivity of the region’s public‑transit network.
