What is the longest tunnel in the world?
The world's longest tunnel is the New York City-West
Delaware water-supply tunnel that runs 105 miles or 169 kilometers from
the Rondout reservoir into the Hillview reservoir, in
Yonkers, New York.
The tunnel was built between
1937 and 1944, has a diameter of 13 1/2 feet and carries 1.4 billion gallons of
water to help quench the thirst of thirsty New Yorkers on a daily basis.
