Motorists could be facing some traffic headaches over the next couple of months as the final round of construction comes to the Highway 40/401 overpass.
Starting today, the MTO is beginning the final phase of work on the interchange.
Officials say there will be intermittent single lane closures on the 401 both east and westbound, day and night single lane closures on Highway 40, and nightly closures of the on and off ramps.
The re-paving work is expected to be done by the end of June.
