Bosphorus Bridge

The Bosphorus Bridge (Boğaziçi Köprüsü), known officially as the 15 July Martyrs Bridge (15 Temmuz Şehitler Köprüsü) and colloquially as the First Bridge (Birinci Köprü), is the southernmost of the three suspension bridges spanning the Bosphorus strait (Turkish: Boğaziçi) in Istanbul, Turkey, thus connecting Europe and Asia (alongside 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 long with a deck width of . The distance between the towers (main span) is and the total height of the towers is . The clearance of the bridge from sea level is . Upon its completion in 1973, the Bosphorus Bridge had the fourth-longest suspension bridge span in the world, and the longest outside the United States (only the Verrazano-Narrows Bridge, Golden Gate Bridge and Mackinac Bridge had a longer span in 1973). The Bosphorus Bridge remained the longest suspension bridge in Europe until the completion of the Humber Bridge in 1981, and the longest suspension bridge in Asia until the completion of the Fatih Sultan Mehmet Bridge (Second Bosphorus Bridge) in 1988 (which was surpassed by the Minami Bisan-Seto Bridge in 1989). Currently, the Bosphorus Bridge has the 40th-longest suspension bridge span in the world. After a group of soldiers took control and partially closed off the bridge during the military coup d'état attempt on 15 July 2016, Prime Minister Binali Yıldırım proclaimed on 25 July 2016 the decision of the Cabinet of Turkey that the bridge will be formally renamed as the 15 Temmuz Şehitler Köprüsü (July 15th Martyrs Bridge) in memory of those killed while resisting the attempted coup. The Bosphorus Bridge is famous for its important transport routes, connecting parts of Europe to Turkey. The idea of a bridge crossing the Bosphorus dates back to antiquity.
