Ambassador Bridge

-A A +A
1927–1929, Jonathan Jones for McClintic-Marshall Company. 21st St. across the Detroit River to Windsor, Canada

Although never as famous as the Niagara suspension bridge, the Brooklyn Bridge, or the Golden Gate Bridge, the Ambassador is Michigan's second-most spectacular bridge, after the Mackinac Straits Bridge ( EM21). When completed to the designs of Jones, chief engineer for the McClintic-Marshall Company of Pittsburgh, it was the longest suspension bridge in the world. It extends 9,602 feet, with approaches. The bridge links the United States and Canada. At night its cables are outlined with strings of twinkling lights.

The Detroit–Windsor border handles more traffic than any other crossing between the United States and Canada. In 2007 traffic over the bridge comprised 9.4 million vehicles. In 2010 Manuel Moroun and the Detroit International Bridge Company, owner of the bridge, proposed a second bridge, a six-lane, 6,200-feet-long span one hundred feet west of the existing bridge and eventually replace the old bridge.
