The Ambassador Bridge spans 1,850 feet over the Detroit River connecting Detroit, Michigan in the United States, with Windsor, Ontario in Canada. With a total bridge length of 7,500 feet, the Ambassador Bridge had the longest suspended span in the world when it was constructed in 1929. More than 25% of all commerce between the U.S. and Canada crosses this long-span connection, making it the single busiest international land border crossing in North America, according to the Federal Highway Administration.
