In 2027 this prestigious project is supposed to connect the Black Sea, Marmara Sea and Mediterranean and bring “luck and prosperity”. It is “a crazy idea”, says the President of Turkey – but the largest construction project in the history of modern Turkey is supposed to “save the future of Istanbul”. Strong words and a great promise that he makes to the residents of the city of 16 million on the Bosporus: A second canal is to be built parallel to the natural waterway of the Bosporus across Istanbul. An artificial waterway, 45 kilometers long, 275 meters wide and 20 meters deep, which will lead from Karaburun on the Turkish Black Sea coast to Kücükcekmece on the Marmara Sea. Six years of construction are planned.
