Olympia Odos


Olympia Odos is a toll motorway system on the Peloponnese in Greece. Starting from Eleusis in the Athens metropolitan area, the Olympia Odos motorways follow the Gulf of Corinth to the Rio–Antirrio bridge and the city of Patras, and along the Ionian Sea coastline, in future down to Tsakona in the southwestern Peloponnese where it will intersect with the Moreas Motorway.
Olympia Odos consists of two highways:
The motorway will be a toll-road linking Athens to Patras and, in the future, to Pyrgos in the west of the Peloponnese.

History

On 4 August 2008 a public-private partnership deal came into effect with the Greek state conceding construction and 30 years of maintenance of the Olympia Odos motorway to the international Olympia Odos S.A. consortium. In return for the right to collect tolls, the consortium will invest a total of €2.8 billion for construction and modernization of the highway.
The upgrade of the A8 and the southern section of the A5 by Olympia Odos S.A. has been described as "the largest and most challenging project currently undertaken in Greece, and one of the most complex ones in Europe.". It also includes the construction of of tunnels and twenty interchanges.
Subsequently, preexisting dual carriageway of the Patras bypass and the National Road 8a section Elefsina–Corinth) were further upgraded to full motorway standards. of preexisting single carriageway in the Corinth – Patras section were doubled. of the southern A5 section will be newly constructed.
The project was expected to take six years to complete, with a completion date scheduled for the end of 2014. The Greek government-debt crisis however led to considerable delays. The overall progress of the project in April 2017 was at 95%.
