The Ambassador Bridge is a privately-owned suspension bridge that connects Detroit, Michigan, in the United States, with Windsor, Ontario, in Canada. The Detroit-Windsor Tunnel also connects these two cities.

The bridge, over the Detroit River, had the largest central span in the world when it was completed in 1929 — 1,850 foot (564 m). The total bridge length is 7,500 feet (2,286 m). The roadway rises 152 feet (46 m) above the Detroit River. It is the busiest international border crossing in North America in terms of trade volume: more than 25% of all merchandise trade between the United States and Canada crosses the bridge.

It is a four-lane bridge and carries more than 10,000 commercial vehicles on a typical weekday. Jointly owned by the Detroit International Bridge Company and the Canadian Transit Company the bridge will have direct access to and from Interstate 75 and Interstate 96 on the U.S. side and Highway 3 on Canadian side when a major redesign of its U.S. Plaza is completed in 2008.

Due to the extremely high traffic volume, the American and Canadian governments are jointly examining proposals for the construction of a second bridge Downriver. Additionally, much of the passenger car traffic has shifted to using the Detroit-Windsor Tunnel because of back ups that extend onto Interstate 75

It was featured in the Eminem movie 8 Mile, Crossing the Bridge, starring Stephen Baldwin, and Grosse Pointe Blank starring John Cusack. It can also be seen in the opening scenes of Four Brothers.
