The Black Sea–Aegean Sea Corridor will consist of three branches. The western route will pass through Athens, Thessaloniki, Sofia, Vidin, Calafat, Craiova, and Bucharest. The central branch will connect Thessaloniki and Alexandroupolis with the Bulgarian cities of Svilengrad and Ruse, then continue through Giurgiu and Bucharest to the city of Siret on the border with Ukraine, as well as to Ungheni on the border with Moldova. The eastern branch will connect Alexandroupolis with the Bulgarian ports of Burgas and Varna, and then with the Romanian port of Constanța, according to Ukrainian Shipping Magazine.
To coordinate the project, the three countries are establishing the Black Sea–Aegean Corridor Platform (BACP), which will serve as a regional mechanism for planning and implementing cross-border infrastructure projects. The main goal of the initiative is to ensure uninterrupted logistics connections between the three sea basins and to integrate the region into the EU’s unified transport system.
According to European Commissioner for Transport Apostolos Tsitsikostas, deepening cooperation will improve transport connectivity for businesses and citizens, as well as strengthen Europe’s security, competitiveness, and sustainability in the Aegean, Black Sea, and Danube regions.
The project’s significance has increased substantially since the start of the full-scale war in Ukraine. Thanks to the central branch’s extension to the Romanian-Ukrainian border, the new corridor could serve as an extension of Ukrainian logistics routes and be used not only for commercial transport but also to ensure military mobility. The countries intend to present a joint implementation and financing plan for the project by the end of 2026, according to ukragroconsult.
