A Engenharia Extrema da Ponte Rio-Niterói: Como Eles Fizeram o Impossível?

The Rio-Niterói Bridge is one of the world's greatest engineering monuments, but what lies hidden beneath the waters of Guanabara Bay? In this documentary, we uncover the extreme challenges, the technology of compressed air caissons, and the immense human sacrifice behind the construction of this megastructure that transformed Brazil in the 1970s. Understand how the prestressing of the beams and the giant concrete voussoirs overcame one of the most unstable soils on the planet! 🔔 If you are fascinated by megastructures and the secrets of engineering, like and subscribe to Barjachi so you don't miss our next documentaries! #Engineering #RioNiteroiBridge #Megastructures #HistoryOfBrazil #CivilConstruction #Documentary
