The Gordie Howe International Bridge opened to traffic on July 29, 2026, but certain trucks remain prohibited from crossing the span [1].
This restriction prevents the new infrastructure from immediately relieving congestion on local roadways, as many commercial vehicles must continue using existing border crossings. The delay in full truck integration means that resident neighborhoods continue to face the traffic burdens the bridge was intended to solve.
Transport Canada and U.S. Customs officials have implemented safety and regulatory restrictions that specifically target trucks carrying hazardous materials or oversized loads [1]. These vehicles are required to use existing crossings until the bridge authority grants additional approvals [1].
Despite these limitations, the bridge saw significant early activity. Approximately 7,500 vehicles crossed the bridge on its first day of operation [2].
While the bridge provides a new link between Windsor, Ontario, and Detroit, Michigan, the impact on local traffic is mixed. Trucks that cannot use the new span continue to crowd Huron Church Road [1]. This creates a contradiction in the initial rollout, where the bridge serves as an alternative for passenger vehicles and some commercial traffic while others remain diverted to the Ambassador Bridge [1].
Officials said they have not yet provided a specific timeline for when the restrictions on hazardous materials and oversized loads will be lifted. For now, the bridge operates as a partial solution to the border bottleneck, providing relief for thousands of commuters while leaving the most complex commercial shipments on the old routes [1].
“Certain trucks, especially those carrying hazardous materials or oversized loads, are prohibited from crossing”
The partial restriction of commercial traffic suggests that the full economic and logistical utility of the Gordie Howe International Bridge depends on regulatory synchronization between Canada and the U.S. rather than just physical completion. Until hazardous and oversized loads are approved, the bridge cannot fully eliminate the heavy-industrial traffic from residential corridors like Huron Church Road, meaning the promised environmental and traffic relief for the city of Windsor will be gradual rather than immediate.
