Ambassador Bridge

The Ambassador Bridge is North America’s #1 international border crossing. It spans the Detroit River, connecting Detroit, Michigan with Windsor, Canada.

Approval for the Ambassador Bridge was granted by acts of both the Congress of the United States and Canada’s Parliament. At the time of its completion in November of 1929, the Ambassador Bridge was the longest suspension bridge in the world, exceeding by 100 feet the Philadelphia-Camden Bridge completed in 1926.

Nearly 25% of all merchandise trade between the United States and Canada crosses the bridge

It is the busiest international border crossing in North America in terms of trade volume: nearly 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.

Due to the extremely high traffic volume, the American and Canadian governments are jointly examining proposals for the construction of a second bridge downriver.
