Under the City: The Wondrous World Beneath the Streets

Hidden beneath the paved streets of American cities lied a fascinating world that few people ever see. There are thousands of miles of steam and sewer pipes, water mains, electric and telephone cables; underground garages and concourses; vast networks of subway trains and railroad lines; tunnels for cars and trucks; and carefully guarded bank vaults set in tons of concrete. In some areas of New York City it's so crowded under the street, you couldn't fit as much as a lead pencil.

If you've ever wondered what the complicated tangle of mains and conduits look like and how the cables are installed and repaired; how cavernous subway tunnels are dug 250 feet beneath the ground; or even what it's like to be in a roomful of gold, you'll be delighted with this unusual tour.
