BRIDGE OF FIRSTS
The 3rd Bridge, which is going to be built on the Bosphorus, Istanbul within the Northern Marmara Motorway Project executed by IC Ictas – Astaldi Consortium, is considered the future of transportation and commerce.
The 3rd bridge, which is going to be built on the Bosphorus, Istanbul after the Bogazici Bridge, which started operating in 1972, and the Fatih Sultan Mehmet Bridge, which was completed in 1988, is regarded as the bridge of firsts.
THE 3rd BOSPHORUS BRIDGE
8 lanes of motorway and 2 lanes of railway will be located at the same level on the 3rd Bosphorus Bridge, which will be a product of professional engineering and advanced technology built by a team, most of whom are Turkish engineers. It will be among the most important bridges of the world with its aesthetic and technical features.
The bridge of firsts , the 3rd Bosphorus Bridge is going to be the widest suspension bridge in the world with a width of 59 meters and the longest spanning one that has a rail system on it, with a main span of 1408 meters. Another first of the bridge is that it is the suspension bridge with the highest tower of the world, with a height of more than 322 meters.
The 3rd Bosphorus Bridge: Symbol of Modern Turkey
With its construction commencing in 2013 and aimed to be completed in 2015, the 3rd Bosphorus Bridge is going to be located in the Odayeri – Paşaköy section of the Northern Marmara Motorway project. The rail system on the bridge is going to transport passengers from Edirne to Izmit. The rail system is going to be integrated with the Marmaray and the Istanbul Subway to link Atatürk Airport, Sabiha Gökçen Airport, and the 3rd Airport which will be constructed.
The Northern Marmara Motorway and the 3rd Bosphorus Bridge is going to be executed with “Build- Operate – Transfer” model. With an investment value of 4.5 billion TL, the project’s operation, including construction, is going to be executed by IC İçtas – Astaldi Consortium for a period of 10 years 2 months and 20 days and then be transferred to the Ministry of Transportation at the end of this period.
The Northern Marmara Motorway and the 3rd Bosphorus Bridge Project will be one of the symbols of modern Turkey and will bring Turkey closer to its objective of being one of the biggest 10 economies of the world in 2023.
About the 3rd Bosphorus Bridge Concept Design
The concept design of the 3rd bridge, which is going to be built on the Bosphorus, İstanbul within the Northern Marmara Motorway Project, has been made jointly by structural engineer Michel Virlogeux, regarded as the “French bridge master”, and Swiss Company, T-Engineering.
Some of the bridges bearing Virlogeux’s signature as one of the most experienced names in the world for bridge design are: Vasco de Gama Bridge, one of the longest bridges of Europe with a length of 17.2 kilometres, located on Tejo River in Lisbon, capital of Portugal, and Normandy Bridge, located on the Seine River in France, which held the title of the longest suspension bridge in the world for 4 years after 1st January 1995, when it was built.
NORTHERN MARMARA MOTORWAY
Northern Marmara Motorway of nearly 115 km length, which has 19 junctions and linking roads, is located in Odayeri – Paşaköy part of the project.
This motorway project is one that covers the 3rd Bosphorus Bridge which was put out to tender on 20.04.2012 with Build – Operate – Transfer model and is planned to be finished in 2015 to relieve the traffic load of Odayeri – Paşaköy lane, and the 1st Bosphorus Bridge and the 2nd Bosphorus Bridge, which are still in use, and to resolve the transportation problem of Istanbul.
