The Gordie Howe International Bridge, which links Windsor and Detroit, officially opened to traffic on July 27. Early data suggests a high volume of motorists utilized the new crossing during its inaugural week.
The first five days: 37,000 cross-border trips
The new Gordie Howe International Bridge saw significant immediate use from both Canadian and American motorists during its first five days of operation. According to Statistics Canada, preliminary inbound figures recorded 18,900 Canadian resident return trips from the United States, alongside 18 ,100 trips by U.S. residents entering Canada.. The data also showed that 4,100 commercial transport trucks entered Canada via the new route in the final days of July.
This surge in activity represents a substantial portion of the regional border traffic. As reported by The Canadian Press, the Gordie Howe bridge accounted for approximately 44 percent of all land crossings from Detroit to Windsor during that initial five-day window. For comparison, the existing Ambassador Bridge and the Windsor-Detroit Tunnel recorded a combined 52 ,700 inbound trips over the same period, though Statistics Canada did not provide a specific breakdown between those two major crossings.
The US$3.5 billion Michigan export decline
The opening of the new bridge comes at a time of significant economic contraction for the Michigan-Ontario trade corridor. A recent analysis from the Canadian Chamber of Commerce revealed that total export values from Michigan to Canada dropped from US$24.4 billion in 2024 to US$20.9 billion in 2025.. This US$3.5 billion decline has had a tangible impact on the workforce,with Michigan losing 15,600 jobs in sectors heavily reliant on Canadian exports, most notably within the automotive industry.
Canadian exports to Michigan have also faced a downturn, falling from $41.2 billion in 2024 to $39.6 billion last year.. While the automotive sector remains the primary driver of these losses, the decline has spread to other critical industries, including base metals, plastics, and the pulp and paper sectors. These figures highlight the vulnerability of the integrated production systems that rely on the Windsor-Detroit border.
The uncertainty of "steady state" volume amid tariff threats
Economic experts are questioning whether the high initial traffic numbers reflect a permanent shift in transit patterns or merely the novelty of a new crossing. Marwa Abdou, senior research director at the Canadian Chamber of Commerce,noted that while passenger vehicle drivers might be drawn by the new route, it remains to be seen if exporters will provide a consistent "steady state" of traffic. The central question is whether the bridge will provide a genuine diversion from the Ambassador Bridge or if it will simply offer an additional layer of choice in an increasingly volatile trade environment.
The long-term utility of the bridge is also threatened by looming political tensions between Ottawa and Washington. Canadian trade officials are currently negotiating in Washington ahead of an August 19 deadline set by the Trump administration, which could see new 50 percent tariffs placed on various Canadian goods. Marwa Abdou argued that while the bridge reduces the physical hurdles of transport, any economic advantage gained through better infrastructure could be erased by the high costs of a renewed tariff dispute.
A 15-year revenue split to end political acrimony
The Gordie Howe International Bridge project was delayed for months due to political disagreements regarding its financial structure. Although Canada funded the construction of the bridge, the project only moved toward completion after Ottawa reached a deal with Washington to split net toll revenues over the first 15 years of operation. This revenue-sharing agreement was a key requirement to resolve the political acrimony that had previously stalled the long-anticipated connection between Windsor and Detroit.
