To relieve traffic on the aging Île-aux-Tourtes bridge as it undergoes a round of repairs, one westbound lane will allow eastbound traffic to Montreal during the morning rush hour.

The direction change began today and will be in effect weekdays from 4:30 a.m. to 10 a.m., according to Quebec Transport Minister Robert Poeti.

Outside those hours, the lane will return to serving westbound traffic.

The speed limit on the bridge has also been reduced to 70 kilometres an hour.

The bridge on Highway 40, which connects Montreal to Vaudreuil-Dorion, has had one of three eastbound lanes closed since Dec. 18. The lane was closed for repairs when a crack was discovered in the structure during an inspection.

Repairs will continue for the next eight to 10 weeks, Poeti said.

"It's still a safe bridge and in no way are users' safety in peril," the minister said during a news conference Monday.

Since the repairs began, an additional car has been added to the Vaudreuil-Hudson train by the Agence métropolitaine de transport.
