Mega Movers

Bridges have been pushed, airlifted and taken apart, but if needed, can one of the world's longest and most famous suspension bridges be moved?

They are miracles of engineering dating back thousands of years -- remains of ancient structures around the world that seem too heavy to move.

Their soaring height is imposing. Their narrow design makes them some of the most difficult and dangerous structures to move.

Suppose the world's largest aircraft carrier, the 1,092 feet USS Ronald Reagan, came under enemy attack and was crippled at sea.

The crew risks their lives to salvage four World War II aircraft.

The mighty Queen Mary -- 1,018 feet long and weighing more than 77,500 tons. Since 1967, this dinosaur of ocean liners, and former WWII troop transport ship, sits parked in dry dock.

Brave deadly radiation and nuclear warheads as you dive into the abyss with the crew to raise sunken submarines.

The Denver International Airport is the largest airport in America. Its famous white peaked fabric roof spans a million-and-a-half square feet.

Follow the massive move of the USS Intrepid from its New York City pier to Bayonne, New Jersey.

The world's oceans are graveyards for some of the greatest ships ever built. During the mid-1500's the English warship Mary Rose was sunk by a French cannon.

War inspires ingenuity, and some of the greatest battles have been won or lost based on the work of Mega Movers.

Imagine trying to move a 475,000 pound structure from Texas to Minnesota. Forget freeways, it'll never clear bridges or overpasses.

Ships are routinely sunk for a variety of reasons. Sometimes they are sunk to be kept out of enemy hands or they are decommissioned and turned into artificial reefs.
