The summer holiday season has officially begun across all regions in the Netherlands, with the ANWB anticipating significant traffic, particularly on foreign highways, as many Dutch residents head abroad for their summer vacations.

Heavy traffic congestion has been reported on major roads in Attica, including Kifisos, Attiki Odos, and Kifisias, as travelers begin their May Day long weekend getaway, with many opting for mainland destinations due to unfavorable weather for island trips.

A British-made Mills grenade from World War II, discovered near the Kifisos River in Amfikleia, was safely neutralized by bomb disposal specialists in central Greece.

Athens is planning a triple bypass project on Kifisos via Skaramagas, involving grade-separated interchanges and the completion of the Western Aigaleo Ring Road, to alleviate the city's severe traffic congestion.

Greece is implementing four fast-track interventions to manage traffic congestion on Kifisos. These include signatures for a triple interchange at Skaramagkas by June, a new exit lane from Attiki Odos towards Lamia by late 2026, a 'counter-Kifisos' for heavy vehicles, and coordination with the port of Piraeus.
