What were the problems the engineers faced when designing the Rion Antirion bridge?
The physical challenges in this area made this project unique. The construction challenges are deep strata of weak soil, deep waters, strong winds, strong seismic activities and fault displacement. To overcome all these challenges the engineers came up with unique solutions which make this bridge soo unique.

What forces act on a cable-stayed bridge?
The towers transfer the cable forces to the foundations through vertical compression. The tensile forces in the cables also put the deck into horizontal compression. A cable-stayed bridge, with forces of tension represented by red lines and forces of compression by green lines.
What is the longest cable-stayed bridge and where is it located?
The world’s longest cable-stayed bridge is the 2,680m (main span) JiaShao Bridge spanning the Qiantang River at the mouth of Hangzhou Bay in China. The bridge forms part of the 69.5km Jiaxing-Shaoxing River-crossing Expressway and consists of eight traffic lanes.
What is the purpose of the Rion Antirion Bridge?
Rion-Antirion Bridge is a technology and engineering masterpiece that contributes to economic development on both sides of the Strait of Corinth: the Peloponnese and mainland Greece. Formerly, crossing the Strait required the use of supply vessels and ferries and 45 minutes. The Rion-Antirion Bridge reduces travel time from one shore to
How are bridges built to withstand an earthquake?
The bridge decking is connected to the pylons using jacks and dampers to absorb movement; too rigid a connection would cause the bridge structure to fail in the event of an earthquake and too much lateral leeway would damage the piers. There is also provision for the gradual widening of the strait over the lifetime of the bridge.
What happens to the piers of a sea bridge during an earthquake?
During an earthquake, the piers can move laterally on the sea floor with the gravel bed absorbing the energy. The bridge decking is connected to the pylons using jacks and dampers to absorb movement; too rigid a connection would cause the bridge structure to fail in the event of an earthquake and too much lateral leeway would damage the piers.
How long does it take to cross the Strait of Rion?
Formerly, crossing the Strait required the use of supply vessels and ferries and 45 minutes. The Rion-Antirion Bridge reduces travel time from one shore to the other from 45 minutes to a mere 5 minutes.
