Olympia Odos is one of the most important national strategic projects for the development of the Peloponnese, Western Greece and Epirus.
It connects these three Regions of Attica- Peloponnese and Western Greece and the Greek capital with the most important gate of Greece to Europe, i.e. the port of Patras.
The new, modern and comfortable motorway offers an enhanced and safe connection to the southwestern part of Greece, and in particular to and from the port of Patras, archaeological sites and tourist areas, while it also strengthens export and agricultural production.
In March 2022, Olympia Odos entered a new era thanks to the construction of a new section that will bring Athens closer to Pyrgos and one of the most important historical sites, Ancient Olympia.
The completion of Patras-Pyrgos will trigger a series of beneficial effects on the economic, social and cultural development of the entire region of Western Peloponnese.
The modern motorway will offer easy road access to the area, while it will allow the whole region to rearrange its tourist and development environment, thanks to sustainable economic, environmental and social activities.
Thanks to the integration of Patras-Pyrgos Motorway in the Concession Project, Olympia Odos becomes the third longer motorway in Greece, with a total length of 277km.

*All MSSs are bidirectional (on both directions), except Zevgolatio MSS (only in the direction to Athens).
Since the very first day of the Concession Project, in 2008, the construction interventions started to upgrade the existing sections of the motorway, (Elefsina-Korinthos section and Patras Bypass), which included among others:
To date, 111 bridges, 17 tunnels and 102 retaining walls of existing sections have been inspected, while maintenance, upgrading and repair works have been carried out where necessary, and innovative practices are adopted for the continuous monitoring and inspection of the major structures.
Korinthos - Patras was one of the most difficult projects constructed in Greece, since it was the only motorway which was constructed under traffic.
The widening and reconstruction of Korinthos - Patras section was in some places one-sided and in others two-sided. The particularities of the project were briefly the following:
|The New Korinthos - Patras Motorway in numbers|
|Section||New Korinthos - Patra Motorway|
|Total Length of Tunnels||16 km|
|Motorists Service Stations (MSS)||5|
|Τechnical Bases /TMC||3/1|
|Total Length (km)||120,00|
It is estimated that about 800 people will be employed in the three (3) worksites of Patras-Pyrgos section already developed.
The first 13km section from Midilogli to Kato Achaia consists in the widening of the existing Patras-Pyrgos national road. The remaining 62km are a greenfield construction on a new alignment in Ilida Valley.
The construction under traffic of the first 13km section of the motorway.
