Greece, Bulgaria, and Romania have initiated a 22.8 billion euro infrastructure plan to establish a transport and energy corridor connecting the Aegean Sea to the Black Sea. This initiative involves 25 high-priority projects, including the modernization of railways, roads, ports, and Danube bridges, to strengthen Greece’s role as an energy gateway to the Balkans and Eastern Europe.

While the regional energy security is being bolstered by the Vertical Gas Corridor—which has seen gas transit capacity from Greece to Bulgaria increase by 30%—Bulgaria faces specific hurdles in the transport sector. The country is currently struggling to secure European funding for railway modernization due to a lack of technical expertise and the absence of ready-to-implement projects and necessary documentation required for EU fund applications.
