The story
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 (Elefsina–Corinth–Rio) and the southern section of the A5 (Rio–Pyrgos–Tsakona) 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 19 km (12 mi) of tunnels and twenty interchanges.
Subsequently, 82 km (51 mi) preexisting dual carriageway of the Patras bypass and the National Road 8a section Elefsina–Corinth) were further upgraded to full motorway standards. 120 km (75 mi) of preexisting single carriageway in the Corinth – Patras section were doubled. 163 km (101 mi) of the southern A5 section (Patras–Pyrgos–Kalamata) 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%.
