U.S.-Canada bridge opens to traffic in Detroit amid Trump tariffs strain

A new six-lane, $6.4 billion bridge connecting Detroit, Michigan, and Windsor, Ontario, opened to traffic on July 27, 2026, providing truckers hauling billions in auto parts a cheaper and more efficient crossing. The opening comes amid ongoing trade tensions and tariff strains imposed by former President Donald Trump, which have complicated cross-border commerce. Detroit remains the busiest US-Canada truck port, and the new span is expected to alleviate congestion and reduce costs for the automotive industry, which relies heavily on integrated supply chains between the two countries. The project was years in the making and represents a major infrastructure milestone for North American trade.
