Marmaray Project

 

 

The Bosphorus (Istanbul Strait) is now crossed by a 1.4-kilometre-long (0.87mi) earthquake-proofed metro line!

It represents the world's deepest undersea immersed tube tunnel and fire resistant concrete which was developed in Norway and crucial for the safety of the project.

New underground stations have been built at Yenikapı, Sirkeci and Üsküdar. Thirty-seven other above-ground stations along the line will also be rebuilt or refurbished. The capacity for the suburban lines is planned for 75,000 passengers per hour in each direction. Signaling has been modernized to allow trains to be as close as two minutes apart, speeding up commuter times. The predicted travel time from Gebze to Halkalı is 104 minutes.

Construction of the Marmaray project started in May 2004. The Marmaray tunnel was completed on September 23, 2008, with a formal ceremony to mark completion of the tunnel on October 13.

After completion, the usage of rail transportation in Istanbul is predicted to rise from 3.6% to 27.7%, making the roads that much quieter! cool
