A Marmaray project, new rail tunnel labeled as the “Project of the century”, links between two continents Europe and Asia, underneath the Bosphorus Strait has been opened in Turkey.
The tunnel is 8.5 miles long, with 1.4km running under the Bosporus, the strait that connects the Black Sea to the Sea of Marmara, and divides Istanbul between Asia and Europe.
Work began in 2004, but archaeological excavations delayed construction.
The Marmaray project will upgrade existing suburban train lines to create a direct link joining the southern part of the city across the Bosphorus Strait.
The submerged tube built by Japan’s Taisei Corp with Turkish partners Nurol and Gama. The bulk of financing came from the Japan Bank for International Cooperation.
“Turkey will celebrate two feasts together,” Transport Minister Binali Yildirim said earlier this month.
“We will mark the 90th anniversary of the republic on October 29 and also realise a one-and-a-half century dream of a major rail tunnel project in Istanbul.”
The Marmaray tunnel project is one of the major transportation infrastructure projects in the world at present. The entire upgraded and new railway system will be approximately 76 km long, according to its official site.
