Kinali-Sakarya Highways

The Kinali-Sakarya Highways is located in Istanbul and includes the Second Bridge Over the Bosphorus.

The artery measures 247 km and links the cities of Kinali (Tracia, European side) and Kazanci, near the Sakarya river (Anatolia, Asian side). The project was divided into four lots. The first includes the construction of 62 km of motorway on the European side, from Kinaly to Mahmutbey; dual-lane carriageways per direction for 51 km, while the remaining 11 km consists of 3-lane carriageways. The second lot included the construction of the second bridge over the Bosphorus, and 37 km of four-lane carriageway motorway links to the bridge. The third lot includes the construction of a 45 km motorway with a two-lane and a three-lane carriageway (from two to three lanes each), on the Asian side, from Çamlica to Gebze. The fourth and final lot includes the construction of a 73 km motorway with a two-lane and a three-lane carriageway, on the Asian side, from Izmit to Sakarya, including spur roads. The Kinali-Sakarya motorway with the Second Bridge over the Bosphorus is one of the most important projects built with a unique contract in the history of the Turkish Republic.
