EKPPT motorway

Olympia Odos, a concession company led by VINCI Concessions, in association with the German company HOCHTIEF PPP Solutions and three Greek construction companies (Aktor Concessions, J&P-Avax, and Athena), has won the largest motorway-concession contract ever awarded in Greece. To achieve this major project successfully, the concession company subcontracted the infrastructure design and construction mandate to us. In efforts to improve traffic conditions in Greece, the country’s minister for infrastructure and transport appointed us to design, build, renovate, and operate (for a 30-year period) 202 kilometres of toll motorway linking Athens and Patras. More specifically, the project calls for designing, building, operating, and maintaining a new motorway with a dual 2-lane configuration between Corinth and Patras (120 km) and Patras and Tsakona (163.7 km) in the Peloponnese. The project also includes upgrading, operating, and maintaining the existing dual 3-lane motorway connecting Elefsina to Corinth (64 km) as well as the Patras bypass (18.3 km).

BACKGROUND

This motorway is considered a required public utility and a priority investment for the trans-European transport network. That is why its development was supported both by the European Commission and the European Investment Bank.
The project, located in southwest Greece, is vital for the country. In this region, where the average income is less than 75% of the average income in Europe, this project reflects a willingness to develop the area’s economy. Investment in these areas is essential, especially in transport and other vital economic infrastructure.

TECHNICAL OVERVIEW

The three leading issues in this project are quality, safety, and environmental protection. Accordingly, following a study of the environmental impact of each motorway segment, studies on the effects of pollution due to traffic (carbon dioxide emissions) were also carried out. These studies show that this infrastructure’s contribution to global warming is minimal. In addition, during the project design, construction, and implementation phases, multiple additional measures were taken to improve the infrastructure’s environmental performance.
The structure was designed to enable quick intervention by security and firefighting services.
The project included other challenges, including maintaining traffic on much of the motorway network during construction, factoring in the presence of several seismic faults, preserving the archeological value of the grounds, and dealing with the proximity of a new railway line leading to Patras.
Another key aspect of this mandate is its international scope. The project is being conducted in Greece by a consortium made up of builders from France, Germany, and Greece. Multiculturalism is present at all levels of this project. Each company brings its know-how and distinct perspective in a cooperative endeavour.

In Greece, both residents and visitors are glad of improvements to transport infrastructure resulting from many past and current projects. This new motorway is part of these improvement efforts.

IMPACT

The project will enhance road connections between the western and northern parts of the Peloponnese, on the one hand, and in the region of Athens and more northerly areas in Greece, on the other. The new infrastructure will connect to the Rion-Antirion Bridge (thanks to the Corinth-Patras section).
The infrastructure will also improve traffic conditions, including shorter travel times and fewer road accidents. To be more precise, the new motorway will reduce average travel time by 20 to 40%.
In addition, the motorway will have a direct economic impact on the regions it runs through and help to improve daily living conditions for the population in these areas, which are remote from the large urban centres and their administrative, economic, and medical services.
Finally, this structure is part of the new generation of motorways: faster, safer, and more environmentally responsible.
