The project of the Ministry of Infrastructure and Transport three-year project connects Aigaleo, National Highway and Attiki Odos, providing a solution to traffic congestion and a new route for trucks.
At the center of the new plan to improve road travel in Attica is the Skaramanga triple interchange, a project of strategic importance that is expected to create new traffic flows, strengthen alternative connections in the Athens metropolitan area, and reduce daily traffic pressure on one of the country’s most congested road corridors. The Minister of Infrastructure and Transportation Christos Dimas presented the next steps for implementing the project, which calls for upgrades to the connections between major road networks and changes primarily concerning the management of traffic involving heavy vehicles.
The Skaramanga triple interchange is part of the solution to the traffic problem on Kifissos Avenue, said the Minister of Infrastructure and Transport, Christos Dimas, on SKAI 100.3 and Nikos Andritsos, Minister of Infrastructure and Transport Christos Dimas.
Relieving traffic congestion on Kifissos Avenue
The contract for this project, Mr. Dimas explained, is set to be signed in early July and is expected to be completed within three years.
The Minister described this as a very significant development, as the interchange will connect the Aegaleo ring road with the National Highway and the Attica Tollway, helping to relieve traffic congestion on Kifissos Avenue and providing an alternative route for heavy vehicles.
“Essentially, we will be removing some traffic lights. The Schistos Bridge will have two lanes, so it will indeed provide an alternative for heavy vehicles, keeping them out of the city center,” he noted.
Regarding the Metamorfosis interchange on Attiki Odos, Mr. Dimas emphasized that the improvements will be completed by 2026.
With the new configuration, vehicles will enter the National Highway from different lanes, significantly reducing traffic congestion.
Other projects
The extension of Kymis Avenue from the Kalliftaki side, aimed at connecting Marousi with the National Highway, remains a proposal in the planning stage; however, it is not an immediate priority due to existing priorities and the high cost of implementation.
Regarding the Metro projects, the minister noted that the second tunnel boring machine, “Niki,” has now passed through Kypseli, having started from Veikou Avenue, and is expected to reach the Evangelismos Shaft by the end of the year.
Regarding the “Fly Over” in Thessaloniki, the minister described it as an innovative project—even by European standards—whose progress has now exceeded 55%.
According to Mr. Dimas, the project will open to traffic in the first half of 2027, doubling the volume of vehicles served.
At the same time, the metro extension to Kalamaria is expected this summer, adding five additional stations to the city’s metro system.
