Because of construction on Route 138 near Highway 20 furthing snarling rush-hour traffic, the Candiac commuter train line will be free for users starting on Monday morning, the regional transport agency for the Montreal region confirmed.
Two additional cars will be added to trains throughout the construction to accommodate more riders, the RTM added.
Car traffic is expected to face added congestion near the Mercier Bridge and officials are advising using commuter trains.
The road work is expected to last until next weekend.
