According to plans, it will run under the Black Sea, from the Beregovaya compressor station in Russia to Varna, and will then split into two branches, with the northwestern one ending in Austria and the southwestern in Italy.
Planirano je da se prostire ispod Crnog mora, od kompresorske stanice Beregovaja u Rusiji do Varne, gde će se račvati u dva kraka - severozapadni koji će se završiti u Austriji i jugozapadni u Italiji.
