This 5,160' (1.6km) long tunnel was built using the immersed tube technique. |
No street view driver wanted to pay a toll and go to Canada. That is, this is as close as they got to the tunnel.
The ventilation towers on each side can supply about 1.5 million cubic feet of fresh air per minute and are patterned after the ventilation system in
New York's Holland Tunnel. The roadway descends 75' (23m) below the river level and has a capacity of 2,000 vehicles per hour. "Completed a year ahead of schedule, costing $23 million. It took 6 months to complete." [
dwtunnel_about] It took 1/3 the estimated time to construct?

Detroit-Windsor Tunnel construction, between 1928 and 1930 | Photo Credit: ITA-AITES The Detroit-Windsor Tunnel, operational since 1930, remains one of the most significant infrastructural connections between the United States and Canada. This international tunnel spans the Detroit River, approximately one mile in length, facilitating transportation and trade activities between Detroit and Windsor. Construction of this engineering landmark represented a collaborative cross-border effort, with a primary objective to streamline transit and commerce. Despite the financial challenges posed by the Great Depression, the project pushed forward, ultimately costing $23 million. Today, the Detroit Windsor Tunnel serves thousands daily, underpinning commercial trade and personal travel. Approximately 12,000 vehicles pass through the Tunnel on a daily basis, handling over four million vehicles per year, of which 98% are cars, 2% are trucks and buses. |

So did they use tubes-in-a-trench under the river, but they bored the tunnel under land?
