Features rare construction footage and interviews with architects, the program climbs to the top of the world's largest towers including Seattle's Space Needle, Canada's CN Tower, and Las Vegas's Stratosphere.

A look up at the symbol of the American Century - the skyscraper; the construction of which is a triumph of engineering and capitalism; climb to the top of the Empire State Building, Chrysler Building, Sears Tower, and World Trade Center.

The art deco Chrysler Building stands out in the New York skyline.

Named one of the seven engineering wonders of the modern age, the Chesapeake Bay Bridge and Tunnel connects Virginia proper with its easternmost landmass; stretching 17 miles across the historic bay, the structure includes highways and islands.

Two ribbons of concrete span the largest inland body of water in Louisiana, forming the world's longest automobile bridge.

The Atlantic Intracoastal Waterway stretches 2,500 miles from Boston to Miami through canals, land cuts, and barrier islands providing protected passage; conceived in late 18th century as America's first superhighway before road systems existed.

The world's largest concrete dam, and the largest concrete structure in the world, lies on the Columbia River in the State of Washington; built in 1931, it is also one of the largest hydroelectric power plants in the world.
