The Great Istanbul Tunnel (Template:Lang-tr) is a proposed multi-use highway and railway undersea tunnel in Istanbul, Turkey to cross the Bosphorus strait.

Project

The project was officially announced by Prime minister Ahmet Davutoğlu on 27 February 2015.[1][2] The tunnel, 6.5 km (4.0 mi) in length and 18.80 m (61.7 ft) in diameter, will consist of three levels, two levels for road traffic and one level for rail system. It will be 110 m (360 ft) under the sea level.[3] Situated between Gayrettepe on the European side and Küçüksu on the Asian side,[3] it will integrate the highways between the three airports of the city, Istanbul Atatürk Airport, Sabiha Gökçen Airport, Istanbul New Airport, and the nine rail lines of the Istanbul Metro.[2] The three bridges over the Bosphorus, Bosphorus Bridge, Fatih Sultan Mehmet Bridge and Yavuz Sultan Selim Bridge, will be linked together through the tunnel.[4] The cost of the project will amount to US$3.5 billion. The financing of the construction will be on the build–operate–transfer basis.[5]

Construction

The RV Fugro Scout, a Singapore-flagged research/survey vessel of 83 m (272 ft) length and 20 m (66 ft) beam,[6] started soil survey works in Bosphorus on 28 July 2017 in order to determine the exact tunnel route.[7]
