Bosphorus Bridge

About

The Bosphorus Bridge (Turkish: Boğaziçi Köprüsü), known officially as the 15 July Martyrs Bridge (Turkish: 15 Temmuz Şehitler Köprüsü) and colloquially as the First Bridge (Turkish: Birinci Köprü), is the oldest and southernmost of the three suspension bridges spanning the Bosphorus strait (Turkish: Boğaziçi) in Istanbul, Turkey, thus connecting Europe and Asia (alongside the Fatih Sultan Mehmet Bridge and Yavuz Sultan Selim Bridge). The bridge extends between Ortaköy (in Europe) and Beylerbeyi (in Asia).

It is a gravity-anchored suspension bridge with steel towers and inclined hangers. The aerodynamic deck hangs on steel cables. It is 1,560 m (5,118 ft) long with a deck width of 33.40 m (110 ft). The distance between the towers (main span) is 1,074 m (3,524 ft) and the total height of the towers is 165 m (541 ft). The clearance of the bridge from sea level is 64 m (210 ft).
