Kanal İstanbul is the Turkish project name of the artificial sea-level waterway, which is proposed to be built by the
Republic of Turkey on the European side of Turkey, connecting the Black Sea to the Sea of Marmara, and hence to the Aegean
and Mediterranean Seas. Kanal İstanbul would bisect the current European side of Istanbul and thus form an island between
the continents of Asia and Europe (the island would have a shoreline with the Black Sea, Sea of Marmara, the new canal and
The new waterway would bypass the current Bosphorus. Kanal İstanbul aims to minimise shipping traffic
in the Istanbul Strait. The project is intended for the 100th anniversary in 2023 of the foundation of the Turkish Republic.
The main purpose of the project is to reduce the marine traffic through the Bosphorus and minimize the risks and dangers associated particularly with tankers. About 56,000 vessels pass yearly through the Istanbul Strait, among them 10,000 tankers carrying 145 million tons of crude oil. International pressure is growing to increase the marine traffic tonnage through the Turkish straits that brings risks for the security of marine navigation during the passage. The canal will further help prevent the pollution caused by cargo vessels passing through or mooring in the Sea of Marmara before the southern entrance of the Bosphorus.
The waterway will have a length of 45–50 km (28–31 mi) with a depth of 25 m (82 ft). Its width will be 150 m (490 ft) on the surface
nd 120 m (390 ft) at the canal bed. These dimensions will allow the largest vessels and even submarines to pass.
The concept of a canal linking the Black Sea with the Sea of Marmara has been proposed at least seven times in history.
The first proposal was made by Ottoman sultan Suleiman the Magnificent (reigned 1520–1568). His architect Mimar Sinan was
said to have devised plans for the project. The project was abandoned for unknown reasons.
On March 6, 1591, during the reign of Sultan Murad III, an imperial ferman (order) was issued and work on the project recommenced, but again for unknown reasons the project was stopped.
In 1654 during the reign of Sultan Mehmed IV, pressure for the recommencement of the canal was applied but to no avail.
Sultan Mustafa III (reigned 1757–1774) tried twice in 1760 but the project could not go ahead due to economic problems.
During the reign of Sultan Mahmud II, an Imperial Ottoman Committee was established to examine the project once again.
A report was prepared in 1813 but no concrete steps were taken.
A completely opposing view was taken in the 1920-52 plan for Atlantropa, which proposed a hydroelectric dam to be built across the Strait of Gibraltar, lowering of the surface of the Mediterranean Sea by up to 200 metres (660 ft). This plan included a dam across the Dardanelles to hold back the Black Sea.
Finally, on January 17, 1994 shortly before the local elections, the leader of the Democratic Left Party (DSP) Bülent Ecevit proposed a canal connecting the Black Sea with the Sea of Marmara.It was not until April 2009, when the Justice and Development Party (AKP) government started discreet studies on the project and concrete steps were taken for the revival of the project. The project was mentioned by Minister of Transport Binali Yıldırım in May 2009 at the parliament.
Prime minister Recep Tayyip Erdoğan announced the Kanal İstanbul project on April 27, 2011 during a rally held in connection with the upcoming 2011 general elections, calling it as his Wild Project (Turkish: Çılgın Proje).
Studies relating to the project were completed within two years. The canal will be in service latest in 2023, the 100th anniversary of
the foundation of the Republic. The project will be financed completely by domestic sources.
The Turkish Prime Minister Recep Tayyip Erdogan and Istanbul Metropolitan Municipality officials have stated that Kanal İstanbul will cost $10 billion to build and that financing for the development has already been allocated by the Turkish Treasury.
They further added that they would be relying entirely on national resources. It is envisaged that Turkish Armed Forces personnel
would play a key role in the Canal’s development.
Commencement of works
On 22 January 2013, the Turkish Government announced that construction of the canal would commence in May 2013. In April 2013 the first stage of the Kanal İstanbul project which includes the construction of various network bridges and highways commenced.
Some critics have stated that Turkey aims to by-pass the Montreux Convention Regarding the Regime of the Turkish Straits and attain greater autonomy with respect to the passage of military ships from the Black Sea to the Sea of Marmara. STRATFOR characterized the announced $10 billion USD construction budget and initial operating date of 2023 as being “not realistic for a project of this magnitude.”
