The Hardest Part Isn't Building a Giant Bridge — It's Moving It. Giant Bridge Construction Machines

Discover how engineers move some of the heaviest bridge structures on Earth into places where ordinary cranes and construction methods cannot work. Watch a 28,000-ton railway bridge rotate above busy tracks, 800-ton girders squeeze through tunnels with only inches to spare, and 2,800-ton precast bridge sections travel from casting yards to open water. From deep foundations and floating caissons to launching girders, modular transporters, floating cranes, suspension bridges and high-speed railway viaducts, this engineering documentary reveals how China, Turkey, South Korea and the United States build enormous bridges while trains, ships and road traffic keep moving.
