Rio–Antirrio bridge przez tsak_d

Due to the peculiar conditions of the straits, several unique engineering problems needed to be considered. The water depth reaches 65 m, the seabed is mostly of loose sediment, the seismic activity and possibility of tectonic movement is significant, and the Gulf of Corinth is expanding at a rate of about 30 mm a year. For these reasons, special construction techniques were applied. The piers are not buried into the seabed, but rather rest on a bed of gravel which was meticulously leveled to an even surface (a difficult endeavor at this depth). During an earthquake, the piers should be allowed to move laterally on the seabed with the gravel bed absorbing the energy. The bridge parts are 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. It was also important that the bridge not have too much lateral leeway so as not to damage the piers. There is provision for the gradual expansion of the strait over the bridge's lifetime.
