As temperatures climb, the first wave of holidaymakers has begun leaving Attica, causing severe traffic jams across the capital’s road network. Significant delays are being reported on Kifisos Avenue, Kifisias Avenue, the Athens–Corinth National Road, and the Attiki Odos motorway.

The worst congestion is currently affecting:

• Kifisos Avenue, northbound toward Lamia, from Renti to Lykovrysi.
• Attiki Odos, between Metamorfosi and Pallini in both directions.

Roads experiencing heavy traffic

Traffic is particularly heavy on:

• Athens Avenue, from Haidari to beyond Lake Koumoundourou.
• Schistou Avenue, near the Skaramangas Shipyards.
• Kifisos Avenue, northbound toward Lamia, from Renti to Lykovrysi.
• Most sections of Alexandras Avenue, with intermittent bottlenecks.
• Kifisias Avenue, in both directions, particularly around the Ring Road (Daktylios) junction.
• Attiki Odos, between Metamorfosi and Pallini in both directions.
• Roads surrounding the Port of Piraeus, where long delays are also being reported.
• Central Athens, especially Stadiou Street, where traffic has become heavily congested.

Attiki Odos travel times

Current delays reported by Attiki Odos:

Towards Athens International Airport:

• 5–10 minutes at the Lamia exit.
• 10–15 minutes from Metamorfosi to Kifisias.
• 10–15 minutes at the Markopoulo exit.

Towards Elefsina:

• Delays exceeding 30 minutes from Kantza to Metamorfosi (Lamia exit).

Central Athens remains congested

Traffic in downtown Athens remains heavy. Earlier today, congestion worsened following a road accident on Panepistimiou Street, where a bus collided with a trolleybus near the Panepistimio Metro Station, leaving four people with minor injuries and causing significant disruption to traffic.

Nearly 19,000 passengers departing from Piraeus

The July holiday exodus is also driving record passenger traffic at Attica’s ports, with ferries departing at high occupancy rates.

According to ERT, nearly 19,000 passengers are expected to depart from the Port of Piraeus today alone. A total of 57 ferry and vessel departures are scheduled, including:

• 23 ferries to the Cyclades, Crete, and the Dodecanese.
• 25 conventional ferries and 32 high-speed vessels serving the Saronic Gulf islands.

In addition, 15 sailings are scheduled from Rafina and 14 from Lavrio.

Passenger traffic at Greece’s largest port continues to increase as the summer holiday season reaches its peak.
