Quebec’s government announced on Tuesday a comprehensive plan to remodel Highway 10 between Brossard and Carignan on Montreal’s South Shore. The proposal calls for the addition of dedicated lanes for buses and high‑occupancy vehicles, alongside upgrades to the road’s aging infrastructure.
The stretch of Highway 10 is a major commuter artery for residents travelling to and from the South Shore. At present, the corridor does not feature any high‑occupancy vehicle lanes, meaning buses and car‑pooling drivers share space with regular traffic. The new reserved lanes are intended to separate these vehicles, creating a faster and more reliable route for public and shared‑transport users.
Officials said the improvements are aimed at enhancing access to the REM rapid‑transit system for South Shore commuters. By providing a smoother link between the highway and REM stations, the government hopes to encourage greater use of public transit and car‑pooling options.
The plan also includes work on the highway’s older sections, which have shown signs of wear over time. Upgrading this infrastructure is expected to improve overall safety and durability of the route, although specific details on the scope of the upgrades were not disclosed.
Highway 10’s role as a key commuter corridor makes the project significant for daily travelers on the South Shore. The addition of bus‑only and car‑pool lanes will address the current lack of high‑occupancy vehicle facilities, potentially reducing congestion during peak periods.
The announcement was made at 15:05 EDT on June 30, 2026. Further steps, including detailed design work and timelines for construction, are to be outlined by the provincial government in the coming weeks.
