Mind Blowing StructuresNational Geographic | Technology
Rio–Antirrio bridge has the longest span of any cable-stayed-bride in the world it faces challenges that would destroy than ordinary bride. The water is too deep, the seabed too soft and and earthquake fault line cuts through the middle. How to design a bride to overcome nature's worst? What does it take to build one of the world's mega-bridges?
The gulf of Corinth in Greece is deep, wide and long with great attributes for marine traffic, but a nightmare for those traveling by land. The Gulf of Corinth virtually chops Greece in two. The only land route between Southern Greece and the West Europe is 240 kilometers east. Bridging the gulf has been a goal for more than a century but has never been possible until now. This is the bridge that is the first ever to cross the Gulf of Corinth.
It clears the water by more than 50 meters leaving plenty of room for even the biggest ships. The design of the bridges looks deceptively simple, 368 sleep cables, 4 conical towers and a yellow ribbon of roadway that glow at night. But the truly amazing thing about this bridge is how it came to be build here in the first place. Challenges of building bridge here was so mind blogging but they stumble engineers for decades. The biggest challenge was earthquake. Bridges has been built across the earthquake zone before but this bridge has to be built cross and active fault line. On top of that the water is extremely deep, 60 meters deep. No other bridge has been build with foundation to that dept before. It would take a daring plan to overcome this hurdle.
