The Ontario government has awarded a contract for the replacement of two highway overpasses in Oshawa to Dufferin Construction Company.

The work to replace the Park Road and Cubert Street overpasses in Oshawa is the first of a series of steps that the province plans to take to widen Highway 401 to 10 lanes.

Dufferin’s contract also includes resurfacing the eastbound lanes of Highway 401 from east of Harmony Road to Courtice Road.

“Our government is investing billions of dollars in highway infrastructure that will support our growing population, and keep vehicles moving,” said Ric Bresee, Parliamentary Assistant to the Minister of Transportation. “Replacing Highway 401 overpasses in Oshawa is a critical step in our plan to widen the 401 so we can tackle gridlock, grow our economy in the face of unprecedented tariffs, and support the drivers and businesses who rely on this highway every day.”

The project will support hundreds of jobs during construction in the engineering, construction and supply chain industries.

“Today marks a major milestone for Oshawa,” said Mayor Dan Carter. “The replacement of the Park Road and Cubert Street overpasses is more than just infrastructure—it’s a strategic investment in our city’s future.”

More than 10,000 trucks use Highway 401 each day, transporting $380 million worth of goods.
