The mega projects in Istanbul in the agenda of Turkey are as follows: The 3rd Bridge, the project within the scope of the North Marmara Highway project will be located on the North part of Bosphorus in Istanbul, it is located in the section of Odayeri - Paşaköy and provides transition from Garipçe to Poyrazköy. It is planned to carry passengers from Edirne to Izmit with the railway system in integration with the North Marmara Highway. It is also considered to integrate the Railed System that is planned to pass over the Bridge, with Marmaray and the Istanbul Metro. When previous examples in the past are reviewed during evaluation of a project of this scale, it is observed that the 2nd Bridge, “The Fatih Sultan Mehmet Bridge”, had a significant share in development of Istanbul towards north and that the new settlement areas had been formed with this bridge which allowed  the new sub-centers to be formed in Istanbul in time.

Consequently, it is expected that opening of the 3rd bridge project in Istanbul will maximize the development of the city in the north and that development of settlement areas will be parallel to this line. Within this framework, it is expected that the prices of lands and fields on this axis will increase and also an increase is expected in zoning plans and number of construction areas. Construction of the 3rd Airport is expected to be made on the European side of Istanbul, by the coast of Black Sea, on the area between the villages of Yeniköy and Akpınar. This new project in Istanbul is foreseen to be one of the largest airports in the world with a transportation capacity of 150 million people. Along with the 3rd airport, a railed system project to be integrated with it is also considered. Development of the city towards North will continue when the 3rd airport is taken into operation and this development will be supported by residential areas, commercial areas and transportation projects in Istanbul. Repositioning of the Atatürk Airport in Yeşilköy after the 3rd airport project will also be a new mega project that can influence the urban scale in this respect.
