Map with all coordinates: The Detroit-Windsor Tunnel passes under the Detroit River and connects Detroit ( Michigan ) in the United States Windsor ( Ontario ) in Canada . The tunnel was completed in 1930.
After the nearby Ambassador Bridge , it is the busiest border crossing between the USA and Canada with over 28,000 vehicles per day . A 2004 study showed that 150,000 jobs and $ 13 billion in annual economic output in the area depend on the Windsor-Detroit Tunnel.
The Detroit-Windsor Tunnel was the third underwater tunnel in the United States when it was built. It is 1573 m long. At its lowest point, the two-lane carriageway is 23 m below the water level of the river.
The tunnel is currently owned by Detroit-Windsor Tunnel LLC, a joint venture between the cities of Windsor and Detroit, which each have a 50% interest. Detroit had considered selling its half to Windsor to enable a tunnel authority. This did not happen because of an administrative scandal.
The Detroit-Windsor Tunnel is the third underwater tunnel in the world between two nations, and the first international underwater tunnel for motor vehicles. The Michigan Central Railway Tunnel , which also runs under the Detroit River, was completed in 1910, making it the second tunnel between two nations. The first international tunnel was the St. Clair Tunnel , which opened in 1891 between Port Huron, Michigan and Sarnia, Ontario. The Detroit-Windsor Tunnel was added to the List of Historic Civil Engineering Landmarks by the American Society of Civil Engineers in 1982.
