The Ambassador Bridge is an international suspension bridge across the Detroit River that connects Detroit, Michigan, United States, with Windsor, Ontario, Canada. Opened in 1929, the privately owned toll bridge is the busiest international border crossing in North America in terms of trade volume, carrying more than 25% of all merchandise trade between the United States and Canada by value.
The bridge is one of the few privately owned US–Canada crossings; it was owned by Grosse Pointe billionaire Manuel "Matty" Moroun, until his death in July 2020, through the Detroit International Bridge Company in the United States and the Canadian Transit Company in Canada. In 1979, when the previous owners put it on the New York Stock Exchange and shares were traded, Moroun was able to buy shares, eventually acquiring the bridge. The bridge carries 60 to 70 percent of commercial truck traffic in the region. Moroun also owned the Ammex Detroit duty-free stores at both the bridge and the tunnel. The Moroun family had sought to stop the Gordie Howe International Bridge between Windsor and Detroit, arguing that it infringes on their alleged exclusive right to collect tolls. Moroun's son, Matthew, is the current owner.
