Project Impossible

Throughout history, mankind has built amazing structures, engineered to overcome unique challenges. Now, 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, a next-generation sports stadium inspired by an ancient Roman temple, and a bridge being raised while it stays open to traffic. This is Project Impossible: Super Structures.

A new class of superstorms could cause great cities like New York to simply disappear. On this episode: Venice flood barrier; underground Tokyo water diversion tunnels; storm defense; Tsunami Machine.
