PEEL—If you thought the commute along Highway 410 was hard now, you might want to brace for the traffic headaches to come as the province embarks on major roadwork.

Ontario’s Transport Ministry confirmed Tuesday that road crews are gearing up to start on new improvements to the highway, including adding High Occupancy Vehicle (HOV) and general-purpose lanes in addition to commuter parking lots in Brampton and Mississauga.

The project starts next month and is expected to wrap up in 2018. The work will cover north and southbound lanes and stretch some 12 kilometres from Highway 410 and 401 in Mississauga to Queen Street in Brampton.

Astrid Poei, spokesperson for the ministry, said notifications will show up along the highway in late August just to let motorists know of what’s to come.
