Presentation of the project

Olympia Odos is the Elefsina – Korinthos – Patra motorway, a total of 201.5 km. It is one of the most difficult construction projects in Greece, since it is the only motorway of which a large part (Korinthos – Patra) is was constructed while in operation.

• The Korinthos – Patra section of Olympia Odos was constructed under a particularly unstable geological environment. The new motorway “embraces” the north coastline of the Peloponnese, making the project a “library” for retaining structures, since all known methods and their combinations are being used here. About 400 retaining structures were needed in this section of the motorway alone.
• The 350 major structures (tunnels, bridges, overpasses and underpasses) are not only spectacular constructions but also contribute to safe and rapid transportation.
• The motorway has a total of 29 interchanges connecting the rest of the road network and making traffic on the highway safe. This is the most dense network of junctions, since on average there is an interchange corresponding to every 7 kilometers of motorway.

From the very first day of the concession comencement, works began in the existing sections of Elefsina - Korinthos and the Patra Bypass, significant construction interventions have been carried out simultaneously with the construction of the Korinthos – Patra motorway, and the refurbishment works are still ongoing.
