UNDER-WATER TUNNEL
DETROIT TO WINDSOR
(From "The Port's" Representative.) NEW YORK, 20th August.
Another marvel of engineering and air control is the Detroit-Windsor un-der-water tunnel, which ranks with the Holland tunnel under the Hudson River, between New York and Jersey City, and the Oakland-Alamcda tunnel in California. It will be opened to traffic in Octobor.
The tunnel has cost £5,000,000. A mile and a quarter long, it is 45 feet below water level. It has a roadway of 22 feet and an estimated capacity of. 1000 vehicles an hour, being limited to this number by the Customs regulations.
The new subway employs the best features of the New York and Oakland tunnels, with many new achievements added. In the ventilating towers at each end of the tunnel will be giant fans, sis of the blower type and sis of the exhaust type. Fresh air will be pumped in and emitted alongside the roadway, about the level of the ordinary automobile exhaust. Suction fans, operating from the upper duet, will draw foul air through openings in ceiling slabs, where it will be conveyed into stacks in the ventilating buildings. Approximately one million cubic feet of air will be required per minute under maximum operating conditions, and a complete change of air will be made in 90 minutes.
