What is the Length of the Marmaray Tunnel? The first comprehensive feasibility study was carried out in 1987 for the construction of a railway public transport link between the east and west in Istanbul and passing under the Bosphorus.
As a result of the studies, it was determined that this type of connection is technically feasible and cost efficient. The route of today's Marmaray tunnel was chosen as the best among a series of routes. The construction of Marmaray, which includes the Bosphorus tube passage and approach tunnels and the construction of 4 stations, started in August 2004. Although the project was planned to be put into operation in April 2009, due to the prolonged archaeological studies between Yenikapı and Sirkeci, the completion period has been extended until today.
The railway tunnel passing under the Bosphorus, Gebze-Söğütlüçeşme HalkalıIt will join the suburban lines between Kazlıçeşme. Work to improve the suburban lines is still ongoing. With the ceremony on October 29, the opening of the Marmaray tunnel, the part of the project under the Bosphorus, will take place.
What is the length of the Marmaray tunnel?
Marmaray goes underground in Yedikule after Kazlıçeşme; It proceeds along the new underground stations Yenikapı and Sirkeci, passes under the Bosphorus, passes through another new underground station Üsküdar, then rises to the surface at Ayrılıkçeşme and reaches Söğütlüçeşme. The total length of this section is 13,5 kilometers. What is the length of the Marmaray tunnel? We can answer the question of 1,4 kilometers.
Thanks to the Marmaray tunnel, 4 on the Asian and European sides can be crossed in minutes. In addition, with the commencement of the commuter lines on both sides, Gebze and Halkalı distance will be 105, between Bostancı and Bakırköy 37, and between Söğütlüçeşme and Yenikapı will be 12 kilometers. Marmaray will be connected to Istanbul Metro as well as Istanbul-Ankara High Speed Line.
