The Hellinikon Project

The revitalization of Hellinikon, which will develop a total area of 6,200,000 sqm, is one of the biggest projects of its kind in Europe and the most ambitious development project ever undertaken in Greece. The Project has been specifically designed to positively impact the local, regional and national economy, by adding significant new investments, employment opportunities and uses in key areas such as tourism, culture, entrepreneurship, R&D and the environment.
The approximate € 8 bn. investment project is expected to generate 75.000 new jobs during maturity and contribute 2.4% to Greece’s GDP by completion date.
It will include, among other, a 1 km long Cut & Cover with 3 lanes per direction as part of the realignment of the heavy trafficked coastal urban motorway that currently crosses the area facilitating the direct connection of the developed land with the coastline and the beach.

Urban tunnels in Metropolitan area of Athens

The implementation of Athens Metropolitan area Master Plan requires some new road tunnels, which include the following:
