The Turkish-Korean Joint Venture (TKJV) has won a tender for construction of a vehicle tunnel underneath the Bosporus. The TKJV released a written statement Thursday saying the project, expected to cost $1 billion, could be finished within the next four-and-a-half years.

The project will be based on the build-operate-transfer (BOT) model. The tube is anticipated to ease traffic in the city of 15 million.

The new tunnel will be constructed on a two-tier system with traffic flowing in opposite directions. At 14.6 kilometers long, including sections both underwater and above ground, it will start in Sirkeci on the European side and end in Göztepe on the Asian side of the city.

The new tube differs from the first Marmaray tunnel, the construction of which started in 2004, in that it will allow vehicular traffic. Also, in contrast to the first tunnel, which was constructed using the submersion method, the second tunnel will be constructed by use of tunneling equipment.
