Ontario Awards Contract to Expand and Widen Highway 3

ESSEX – To improve road safety and keep people and goods moving in southwestern Ontario, the Ontario government has awarded a contract to design, build and finance the widening of Highway 3 between Essex and Leamington. The highway expansion project is a priority for the province along with plans to help the City of Windsor build a new interchange connecting Highway 401 to Lauzon Parkway.

“This new contract marks an important milestone as we get it done by expanding and widening Highway 3 and connecting Highway 401 to Lauzon Parkway for the growing Windsor region,” said Premier Doug Ford. “Right across the province, our government is making historic investments in roads and highways to tackle gridlock, connect communities and build our economy.”

The Highway 3 expansion project includes:

  • Widening Highway 3 from two to four lanes for 15.6 kilometres between Essex and Leamington;

  • Widening five existing intersections and adding traffic signals to three intersections that currently operate without signals;

  • Permanently closing four side road intersections to improve road safety along the corridor; and

  • Resurfacing existing lanes.

The government is also supporting the City of Windsor by initiating a procurement for an Environmental Assessment and design of a new interchange connecting Highway 401 to Lauzon Parkway. The interchange will support increased opportunities for trade and better access to the Windsor-Detroit border.

“Our government is making it safer and easier to travel in southwestern Ontario,” said Caroline Mulroney, Minister of Transportation. “By advancing critical transportation projects, like the widening of Highway 3, and supporting plans to connect Highway 401 to Lauzon Parkway in Windsor, we’re also supporting economic development and increasing trade opportunities across Ontario’s borders.”

Widening Highway 3 to four lanes from Essex to Leamington is one of 40 projects identified in the government’s Connecting the Southwest: A Draft Transportation Plan for Southwestern Ontario, to better connect communities and create a safe and reliable transportation network.

“Our government continues to build key infrastructure projects faster by embarking on the most ambitious capital plan in Ontario’s history with planned investments of more than $184 billion over the next 10 years,” said Kinga Surma, Minister of Infrastructure. “By widening Highway 3 and investing in other key transportation projects, the province is reducing gridlock, making our commutes safer and easier, and ensuring that our infrastructure is built to last for decades to come.”
