As our northern neighbor, it should come as no surprise that Canada is one of the top trading partners with the United States. Over $664 BN of trade was conducted between Canada and the US in 2021, and nearly a quarter is moved on the Detroit River between the Canadian city of Windsor and Detroit, MI. It is for this reason that a plan for a new bridge linking the two gateway cities began. After more than a decade of planning and preparation, construction of the Gordie Howe International Bridge was started in 2018. Ultimately, the bridge would span over half a mile, with the iconic silhouette of the bridge being set by two A-shaped piers rising 722’ above the river.
