Detroit-Windsor Tunnel, Detroit

3.6
The Detroit–Windsor Tunnel is a highway tunnel connecting Detroit, Michigan, in the United States, with Windsor, Ontario, in Canada. It is the second busiest crossing between the United States and Canada.
ConstructionThe Detroit–Windsor Tunnel was built by the firm Parsons, Klapp, Brinckerhoff and Douglas . The executive engineer was Burnside A. Value, the engineer of design was Norwegian-American engineer Søren Anton Thoresen, while fellow Norwegian-American Ole Singstad consulted, and designed the ventilation.
The method used to construct the tunnel was immersed tube, as was done in the earlier Posey Tube. The tunnel sections have three main levels. The bottom level brings in fresh air under pressure, which is forced into the mid level, where the traffic lanes are located, and the third level is where the engine exhaust is forced into and vented at each end of the tunnel. Total cost of construction was approximately $25 million US dollars.
The river section of the tunnel was connected to bored tunnels on both banks. The tubes were then covered over in the trench by 4to of mud. Because the tunnel essentially sits on the river bottom, there is a wide no-anchor zone enforced on river traffic.
The tunnel is 120ft short of a mile at 5160ft. At its lowest point, the two-lane roadway is 75ft below the river surface.

  • I was born and raised in Michigan and have lived there for 36 years before moving out of state in 1978. I have used the Detroit-Windsor Tunnel many times when visiting Windsor, Canada, usually for a delicious dinner at one of the restaurants. The one mile long tunnel is quickly crossed. While in the tunnel, I frequently saw water dripping along the tunnel walls reminding me that I was under the Detroit river. I always had a happy feeling as I arrived at the tunnel exit after crossing. Most of the time, I used the Ambassador bridge because I drove south to Amherstburg, Ontario to visit my wife's grandparents who owned a farm. The view from the bridge is much nicer than the view in the tunnel.
  • A coming of age tradition for kids 19 to cross and drink. Many countries have these tunnels such as in England Taiwan or here. I like the bridge view but tunnel is faster I discovered. Hope to drive it again.
