Greece signs 36-month, 40.8m euro Skaramangas interchange deal to untangle 100,000 daily vehicles

Signing ceremony caps 8-month preparation

Exactly eight months after Prime Minister Kyriakos Mitsotakis announced the project on 10 November 2025, the contract for the triple Skaramangas interchange was signed on 13 July 2026 at the Botanical Garden of Diomides in Haidari. Minister of Infrastructure and Transport Christos Dimas underscored the pace, noting the government's determination to advance critical infrastructure alongside the Attica Region and regional governor Nikos Chardalias.

The image we behold every time we pass through this area is the image of a region where time seems to have stopped, an abandoned area. Today I have the great honour to attend the signing of an exceedingly important project not only for western Attica but for the whole basin.

Scope: 7.4 km, three bridges, three interchanges

The intervention zone covers 10 square kilometres. The works package includes 7.4 km of new road, three bridges and three grade-separated interchanges at Skaramangas, Schistou and the shipyards (Nafpigeion). Five specific interventions are planned: completion of the Western Peripheral Avenue of Egaleo, upgrade of the Schistou interchange with a new bridge from Athens towards Schisto and reconstruction of the existing bridge towards Corinth, abolition of the signal-controlled Schistou-Palaska junction, and creation of the new Nafpigeion and Schistou interchanges.

Unclogging 100,000 vehicles a day

Roughly 100,000 vehicles traverse Skaramangas each day, nearly 20,000 of them heavy trucks. The new infrastructure will create a dedicated Schistou-Western Peripheral Avenue axis, divert traffic away from the congested Kifissos Avenue, and widen the Athens-Corinth national road to three lanes in the interchange zone. Mitsotakis pointed to knock-on benefits for the port of Piraeus, where heavy vehicles will gain direct access to Attiki Odos, and for the Aspropyrgos area, which he described as being transformed into a logistics centre of European and global scope.

Just think that the Western Peripheral of Egaleo was essentially half-finished. Think how much of a breather we will be able to give to the port of Piraeus when this road can serve heavy vehicles to Attiki Odos and how important it is for the overall development of the Aspropyrgos area which is being transformed into a logistics centre of European and, I dare say, global reach.

Cost, funding, and the race to finish

The signed contract is worth 40.8m euros, while the total project cost is estimated at 60.5m euros and will be funded through the National Strategic Reference Framework (NSRF), Deputy Minister Nikos Tachiaios confirmed. Dimitris Koutras, the head of Domiki Kritis which holds 40% of the consortium alongside METKA (part of the METLEN group), cautioned that timely expropriations of a hotel and a petrol station remain a prerequisite for breaking ground. The contractual timeline is 36 months, though Mitsotakis urged the builders to deliver sooner and the consortium pledged to aim for an earlier finish.

A wider infrastructure push

Mitsotakis linked the Skaramangas project to a series of complex undertakings the government is pushing forward, citing the Thessaloniki flyover scheduled to be completed in the first months of 2027 and the maturing link between Elefsina and Oinofyta. He acknowledged that construction would bring temporary disruption and called on residents to be patient. "We have proven that we can handle complex projects," he said, adding that Greece is turning into "a vast construction site" that is correcting decades-old shortcomings.
