The Paradeisos junction on Kifissias Avenue in Maroussi came into operation yesterday, two-and-a-half months ahead of schedule. Public Works Minister Vasso Papandreou told reporters at the inauguration that works on the Faros interchange in Psychico are also ahead of schedule and could be completed by the end of March. Work on the junctions at Halandri and Aghia Varvara, also on Kifissias, will begin after the Olympics.
