Ontario Looks to Ease Highway 400 Congestion with Major Expansion. What Commuters Can Expect
AECOM will design the 11-kilometre project, which adds four lanes and expands Highway 400 from six to 10 lanes.
- On Monday, Oct. 5, 2026, the Ontario government awarded a detailed design contract to AECOM to widen Highway 400 from six to 10 lanes between Highway 9 and the future Bradford Bypass.
- This 11-kilometre expansion is part of the province's $31 billion infrastructure plan aimed at addressing gridlock and keeping goods moving along this critical route between northern and southern Ontario.
- Transportation Minister Prabmeet Sarkaria stated the project helps "keep our economy moving," while York-Simcoe MPP Susan Lahey noted the widening will "reduce commute times" and support continued regional growth.
- The Vaughan Chamber of Commerce welcomed the investment, with vice-president Abdus Samad stating it is crucial to "support business growth and keep Ontario competitive" given current highway congestion.
- Early work begins next year to link this project with other regional developments, Sarkaria said, including the Bradford Bypass and ongoing bridge construction in Barrie.
