Construction to widen 18 kilometres of the 401 from Mississauga to Milton has begun.
According to the province, the $640 million project is meant to reduce congestion.
“Our government is committed to strengthening Ontario’s highway network and making Ontario open for business,” said Associate Minister of Transportation Kinga Surma. “This crucial expansion of Highway 401 means that thousands of Ontarians will spend less time in traffic and more time on the things that matter to them — being with family, friends, or at work.”
The project will widen 18 kilometres of highway from the Credit River in Mississauga to Regional Road 25 in Milton and includes reconstruction of bridges as well as upgrades to support facilities and features.
With construction being underway, drivers can expect to use the expanded highway by 2022.
Once completed, the province said the expanded highway will include a 12 lane core-collector system from the Credit River to Winston Churchill Boulevard, 10 lanes from Winston Churchill Boulevard to Highway 407 ETR/ Highway 401 interchange, 12 lane core-collector system from Highway 407 ETR/ Highway 401 interchange to James Snow Parkway, 10 lanes from James Snow Parkway to RR 25, and Median High Occupancy Vehicle (HOV) lanes.
There will also be new or improved support facilities and features, such as drainage, lighting, signage, and carpool lots.
Approximately 250,000 vehicles travel on Highway 401 in the Peel and Halton regions on a daily basis, according to the province.
