The Marmaray Project is a commuter rail system designed to unify Istanbul’s two independent rail transportation systems, and it will connect Halkalı on the European side with Gebze on the Asian side of the city. With the beginnings of rail construction in the 1870s, the waters of the Bosphorus separated the Oriental Railway on the European side from the Anatolian and the Baghdad Railway, preventing a direct connection between Europe and Asia.

  • Marmaray Project - Turkey
    MARMARAY PROJECT - TURKEY Istanbul is a city where historical and cultural values must be preserved and at the same time modern railway facilities have to be installed to decrease the environmental impact of public transportation and increase the capacity, reliability and comfort of the railway systems. The Project provides an upgrading of the commuter rail system in Istanbul, connecting Halkalı on the European side to the Asian side with an uninterrupted, modern, high-capacity commuter rail system. Railway tracks in both sides of Istanbul Strait will be connected to each other through a railway tunnel connection under the Istanbul Strait. The line goes underground at Yedikule, continues through the Yenikapı and Sirkeci new underground stations, passes under the Istanbul Strait, connects to the Üsküdar new underground station and emerges at Sögütlüçesme. The entire upgraded and new railway system will be approximately 76 km long. The main structures and systems; include the immersed tube tunnel, bored tunnels, cut-and-cover tunnels, at - grade structures, three new underground stations, 37 surface stations (renovation and upgrading), operations control centre, yards, workshops, maintenance facilities, upgrading of existing tracks including a new third track on ground, completely new electrical and mechanical systems and procurement of modern railway vehicles. The idea of a railway tunnel under the Istanbul Strait was first raised in 1860. However, where the tunnel under the Istanbul Strait crosses the deepest parts of the Strait, the old-fashioned techniques would not allow the tunnel to be on or under the seabed, and therefore the design indicated a "floating" type of tunnel placed on pillars constructed on the seabed.

TERRATEC is pleased to announce that it now has a total of nine machines working concurrently on Istanbul’s Metro system, in Turkey. The on-site assembly of two 6.56m diameter Earth Pressure Balance Tunnel Boring Machines (EPBMs) is currently underway for the Ümraniye-Ataşehir-Göztepe (UAG) Metro line, which is being constructed by the by the Gulermak, Nurol & Makyol JV. These EPBMs, along with another pair of sister machines that have already been assembled for this project, are all due to be launched and mining by mid-May. The 13km-long Ümraniye-Ataşehir-Göztepe (UAG) line, along with its 11 new stations and NATM-built connections, will form a second north to south rail corridor under the densely-populated Anatolian side of Istanbul and will be located entirely underground at an average depth of about 30m.

  • Marmaray - Connecting
    Smart City – Good Practice Transport and mobility Marmaray - Connecting Istanbul's Asian and Ca European side by railway Istanbul, Turkey Marmaray- Connecting Istanbul's Asian and European side by railway The Marmaray railway public transportation system was opened in 2013 in Istanbul [1]. Transportation has been a major problem for Istanbul for many years, especially transportation between the two sides of the city - Asia and Europe - has been a real challenge. Before Marmaray has been implemented the two sides have been connected only by highways (2 Bosporus bridges) and sea transit ferries. The high-tech construction methods used for the Marmaray project helped creating smart solutions for specific challenges in cities. The project was planned already back in 1860, however only today’s technology made it possible to construct and operate it. In the further steps of the project, Marmaray will be connected to the existing railway system of the city [2]. It enables to pass the Bosporus in 4 minutes and to transport 75,000 passengers per hour (Yenikapi station) [3].

  • Chapter 3 Road Network and Traffic Volume
    The Study on Integrated Urban Transportation Master Plan for Istanbul Metropolitan Area in the Republic of Turkey Final Report Chapter 3 Chapter 3 Road Network and Traffic Volume 3.1 Road Network 3.1.1 Inter-regional Road Network 1) Existing Road Turkey is situated at the transit corridor between South-east Europe and the Middle East. Since “The Declaration for The Construction of International Arteries” (AGR) prepared by the United Nations Economic Commission for Europe (UN/ECE) in 1950 in Geneva, Turkey has developed international corridors connecting it to Southern Europe, because the international road network of AGR included an extension to Turkey. According to the provisions of AGR, two arteries should reach Turkey as E-Road. These are E-80 entering from the Bulgarian border (Kapikule) and E-90 entering from the Greek border (Ipsala). These two main routes link the International Road Network of Europe with the Middle East and Asia at southern and eastern borders of Turkey via Anatolia. Source: KGM, Ministry of Transportation Figure 3.1.1 International Road Network through Turkey, 2007 In addition to the E-Roads, the Trans-European Motorway (TEM) project is ongoing and it covers the whole country as an expressway network. The TEM highway network in Turkey starts from Edirne at the Bulgarian border and passes through Istanbul via the Fatih Sultan Mehmet Bridge and parts into two branches in Ankara going eastward and southward. Its eastern branch again parts into two branches in Askale. One of them reaches Trabzon in the Black Sea Region, and the other ends in Gurbulak at the Iranian border.
