Justin crawls under 500 tons of steel to keep the iconic Glasgow Tower turning, and later cruises down Venice’s Grand Canal to find out how a dastardly bridge has been breaking more than just Italian hearts. Meanwhile, Naotomo Umewaka helps engineers in Osaka keep their airport from sinking into the sea, and Daniel Lefevre finds out what’s going to happen to the roaring São Paulo highway that’s been built just centimeters from people's bedrooms.
