Acting on behalf of the Greek State, HOCHTIEF PPP Solutions – in conjunction with partners – is planning, financing, building, upgrading and operating the Maliakos-Kleidi toll motorway. The project involves a section some 230 kilometers in length linking with a further 30 kilometers of national road to form part of the Greek PATHE motorway. This links the two metropolises of Thessaloniki (Salonika) and Athens with the Peloponnese and Patras, the country's biggest port. The Maliakos-Kleidi section is the most important and busiest transport corridor between the Greek capital Athens and Thessaloniki. It runs from Raches in the south on the Maliakos Bay to Kleidi in the north.

With a stake of 35 percent, HOCHTIEF PPP Solutions has the biggest share in the concession company Aegean Motorway S.A. The investment volume for the project is around EUR 1 billion. This will be refinanced by the toll charges and state start-up financing of around EUR 300 million. The private partners will be responsible for this route for a total of 30 years.
