Minimize Rion-Antirion Bridge, Greece

This comparison uses imagery acquired by Sentinel-2 and Landsat-7, with a time difference of 20 years to show the Rion Antirion bridge, Greece.

Rion Antirion is one of the world's longest multi-span cable-stayed bridges and longest of the fully suspended type. Due to the peculiar conditions of the straits, several unique engineering problems needed to be considered and overcome. 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. In addition, the hills on either side create a wind tunnel where 70 mph winds are common.

The bridge was inaugurated on 7 August 2004, a week before the opening of the 2004 Summer Olympics in Athens. Olympic torchbearers were the first to officially cross it.
