The Rio-Antirrio Bridge or as it is officially called Charilaos Trikoupis located near Patras, Greece, is one of the most important accomplishments in modern Greece.
When the project first began, no one could have predicted how difficult it would be to construct and fulfill Charilaos Trikoupis’ wish. The National Geographic Channel recently showed a documentary concerning the difficult feat of making such a bridge.
Charilaos Trikoupis, Greek Prime Minister at the time, had expressed his dream to make a 3km bridge crossing the Gulf of Corinth. Nearly one hundred years later his dream came true in 2004, when the Rio-Antirrio bridge was built, becoming an important landmark of Greece’s 21st Century and a part of the country’s daily life which it eventually changed.
It is the world’s longest multi-span cable-stayed bridge and its construction wasn’t an easy feat. Due to the peculiar conditions of the straits, several unique engineering problems needed to be considered. The seismic activity in the area and the possibility of tectonic movement is significant, and the Gulf of Corinth is expanding at a rate of about 30 mm a year. This is why special measures had to be taken in order to ensure people’s safety. All the techniques are explained in the 50 minute documentary by National Geographic.
