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.
But not this past week.
