The suspension of the blue decorative lighting was announced by the company due to the ongoing electricity crisis in Europe but also to be in line with the company's environmental strategy. The bridge's carbon footprint has been reduced by 84.5% from 2015 to 2022.

with the height of the towers, and the engineering complexity involved in designing and constructing the bridge) and as the latter is also supported by bearings at the pylons apart from cable stays, the Rio–Antirrio Bridge deck might be considered the longest cable-stayed "suspended" deck in the world.

For these reasons, special design and construction techniques were applied. Beneath each pier the seabed was first reinforced and stabilized by driving 200 hollow steel pipes vertically into the ground. The pier footings were not buried into the seabed, but rather rest on a bed of gravel meticulously

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

On 28 January 2005, six months after the opening of the bridge, one of the cable links of the bridge snapped from the top of the M1 pylon and came crashing down on the deck. Traffic was immediately halted. The investigation found that a fire had broken out on the top of the M1 pylon after a
