Quebec Plans Bus and Carpool Lanes on Highway 10

Quebec is planning a major upgrade of Highway 10 between Brossard and Carignan, adding bus and car‑pool lanes to improve access to the REM rail system and reduce congestion. The project forms part of a wider effort to modernise key roadways and boost public‑transit connectivity on the South Shore.

The Quebec government announced plans to overhaul Highway 10 on Montreal's South Shore, adding dedicated lanes for buses and car‑pool vehicles while modernising the road's aging infrastructure. The project will focus on the stretch between Brossard and Carignan, a corridor that serves a large number of commuters traveling to and from the region.

Officials said the new reserved lanes are intended to improve access to the REM commuter rail system for residents of the South Shore. By giving priority to high‑occupancy vehicles and public transit, the province hopes to make the connection between road and rail more seamless, encouraging commuters to shift away from single‑occupancy cars.

The overhaul is part of a broader provincial effort to upgrade key roadways that intersect with the REM network. The government has emphasized that the improvements aim to reduce congestion on routes that feed into the commuter rail, thereby enhancing overall transit connectivity across the region. The focus on Highway 10 reflects its importance as a major artery linking several South Shore communities to downtown Montreal.

While specific timelines for construction have not been disclosed, the announcement signals a commitment to addressing infrastructure fatigue and to supporting sustainable transportation options. The plan aligns with ongoing provincial initiatives that prioritize public‑transit integration and seek to alleviate traffic pressures on heavily used corridors.

Stakeholders are expected to monitor the project's progress as details emerge regarding design, funding, and implementation schedules. The province's approach underscores a shift toward multimodal travel solutions, positioning Highway 10 as a critical component in the future mobility landscape of the South Shore.
