Province replacing two overpasses to accommodate future 10-lane highway that will reduce gridlock and get drivers where they need to go faster


The Ontario government is replacing the Park Road and Cubert Street overpasses in Oshawa to accommodate the future widening of Highway 401 to 10 lanes. The overpass replacements are part of the province’s nearly $30 billion plan to build, expand and repair highways, roads and bridges, helping to protect Ontario’s economy and keep thousands of workers on the job in the face of U.S. tariffs and economic uncertainty.

“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 good-paying jobs during construction in the engineering, construction and supply chain industries. The contract also includes resurfacing the eastbound lanes of Highway 401 from east of Harmony Road to Courtice Road.

“Today marks a major milestone for Oshawa,” said Dan Carter, Mayor of Oshawa. “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. As Oshawa continues to grow, this project will help support local businesses, create good-paying jobs, and strengthen our economy as a whole.”
