Meanwhile, a Greek State Foundation (proposed name ''Athens 508 BC''), will take on the attraction of capitals from the European Union, but also from funding sources in the Greek state, based on the model successfully applied in the past by "Athens 2004" and "Athens Metro". It will take on the design and construction of the project, which will be owned by the Greek state. The two companies will be responsible for the selection of specialized companies which will help complete the project.
