Project Impossible

A new class of super structures are taking on the impossible: the largest moveable building in history, a super-tall skyscraper built to withstand killer earthquakes, and a bridge being raised while it stays open to traffic.

Around the world, engineers are fighting back against a new class of superstorm, raising some of the biggest sea defences in the world. This episode: the Venice flood barrier, Tokyo's underground water diversion tunnels, and New Jersey storm defense.

Across the world, engineers are going to extreme lengths to keep the lights on: harnessing the power of the longest river on Earth, tapping into the raging heat of a live volcano, and building one of the largest offshore wind facilities in the world.

A new breed of tools allows man to face deadly forces once thought impossible. On this episode: a polar survival suit, a thermal imaging fire fighter mask, and a big wave surfing emergency vest.

Toppling giants of concrete and steel is dangerous and deadly. In demolition, one mistake can cost you your life. On this episode: imploding a casino, dismantling chemical weapons and tripping a silo.

America has a history of building the impossible. Across the nation, a new generation of impressive projects is underway. On this episode: New Tappan Zee Bridge, Los Angeles Subway, New Orleans pump station, and Mount Rushmore preservation.
