Why the Ambassador Bridge is crucial to two nations' economies
CNN
The United States' largest trading partner isn't China, or Mexico. It's Canada.
And the Ambassador Bridge, which separates the US and its neighbor to the north, may be the most economically important one-and-a-half miles of roadway in the Western Hemisphere. Until this past week it got very little attention for the crucial role it plays in the economies of the two nations.
A total of $664 billion worth of goods moved between the two countries last year, according to US Commerce Department data. The state of Michigan estimates 30% of the total moved over the privately-owned Ambassador Bridge linking Detroit and Windsor, Ontario. An estimated 10,000 commercial vehicles cross the bridge daily.
