The Yavuz Sultan Selim Bridge (Turkish: Yavuz Sultan Selim Köprüsü), initially named the Third Bosphorus Bridge, is a project to construct a bridge for rail and motor vehicle transit over the Bosphorus, north of two existing bridges in Istanbul, Turkey. The bridge will be situated between Garipçe in Sarıyer on the European Side and Poyrazköy in Beykoz on the Asian side. The foundation stone laying ceremony was held on May 29, 2013.
The bridge is part of the projected 260 km (160 mi) long Northern Marmara Motorway (Turkish: Kuzey Marmara Otoyolu), which will bypass urban areas of Istanbul in the north connecting Kınalı, Silivri in the west and Paşaköy, Hendek in the east. The 58.4 m (192 ft) wide bridge will be 2,164 m (7,100 ft) in length with a main span of 1,408 m (4,619 ft). The main span of the bridge will be 8th longest among suspension bridges in the World.
