The Turkish-Korean Joint Venture (TKJV) made up of Turkey's Yapi Merkezi and South Korean companies SKEC, Samwhan Corp., Hansin, Namkwang Engineering & Construction and Kukdong Corp. as well as a consortium of Turkish firms Cengiz, Makyol and Dogus and France's VINCI submitted their bids in a tender organised by the Railroads, Ports and Airports Construction General Directorate (DLH) of the Ministry for transport. The tunnel, to be constructed under the Bosphorus, will connect the two sides of Istanbul. It will have two levels of traffic and two lanes per direction. Each level will be dedicated to one direction of traffic. Planned to be completed in around three years, the project will consist of tunnelling methods such as advanced TBM technology for the parts under the sea and open cut and NATM for other parts. The total length of the project including connecting roads will be 5.5 km. The length of the TBM tunnel will be 3.34 km, with internal diameter of 11.4 metres and external diameter of 12.4 metres. The NATM cross-section will be 15 m wide and 22 m high, whereas the open cut cross-section will be 10 mwide and 6 m high.

The consortium offered a contract period of 19 years for the tunnel, six years for investment and 13 years for running. The tunnel will be located deeper than the tubes of the Marmaray project, a railway project currently under construction that will also link the two sides of the city. The tunnel, to be constructed under the Bosphorus, will have two levels and two lanes. Each level will be dedicated to one direction of traffic. Click tr/30. Visit www.dlh.gov.tr 34-35/08.

The consortium Italferr (Italy)/Altinok (Turkey) has been awarded the EUR3.9 million contract for the supervision of works and design review of Eurasia Tunnel, the undersea road tunnel that will connect the European and Asiatic sides of Istanbul. The Eurasia Tunnel, about 15 km-long, including 3.4 km below sea level, at a depth of about 25 m, crosses the Bosphorus Strait in parallel with the Marmaray rail tunnel. Once completed, it will allow the connection between the two continents in 15 minutes, compared to the current 100 minutes. The entire project is funded by the European Bank for Reconstruction and Development (EBRD) with a loan of EUR110 million.
