ADRIETA proposes the development of a multimodal transport corridor connecting the Adriatic/Ionian macro-region supply chain with the Black Sea region supporting the priorities set in EUSAIR strategy and taking into acknowledgement E.C. guidelines for the development of the trans-European transport network and the new focus to create a network of strategic core-network corridors with multi-modal connections, which will stretch from East to West and from the geographically peripheral-regions to the centre of EU. ADRIETA has come as a result of the work carried out by a number of operational bodies (ports and transport operators) in the participating countries of the corridor, Greece/Italy/Bulgaria in an attempt to promote interoperable operations with neighbouring countries and eliminate existing technical/operational and administrative bottlenecks ensuring thus a sustainable mobility pattern in the macro-region and beyond.
