Abstract:

When the Sunshine Skyway Bridge over Tampa Bay, Fla., was partially destroyed in an accident twelve years ago, officials at the Florida Department of Transportation decided to replace it with a new, taller bridge that would allow larger ships to enter the harbor. But left over were the remnants of the old twin span bridge, which stretched over the bay. Demolishing the remaining span and the rest of the bridge has been one of the largest demolition projects in U.S. history and it has been carried out by a variety of means, from deep water divers to cutting torches to high explosives. It is also a portent of things to come as government officials on all levels face up to the coming challenge of demolishing large items of decayed or outmoded infrastructure.
