The Golden Horn Metro Bridge (Turkish: Haliç Metro Köprüsü), is a cable-stayed bridge for the metro line M2, spanning the Golden Horn in Istanbul, Turkey that connects the districts Beyoğlu and Fatih. It is built around 200 m (660 ft) east of Atatürk Bridge, between it and Galata Bridge It is the fourth bridge across the Golden Horn and it entered service on February 15, 2014, the bridge enables a direct connection of the end station Hacıosman in the Sarıyer district with the transport hub Yenikapı in the Fatih district.
The appearance of the bridge project in the general agenda goes back to 1952. After approval of the metro line by the city's Monument Protection Board and completion of the tunnels relating to the metro line, a construction bid for the metro bridge spanning the Golden Horn was published by the Metropolitan Municipality. By 2005, a total of 21 proposals were submitted to the Monument Protection Board; however, none were found to be sufficiently in sympath with the city's skyline.
A successful design, by architect Hakan Kıran, was controversial from the very beginning. In November 2009, the tower height was reduced from initially projected 82 m (269 ft) to 65 m (213 ft) because the original height threatened the removal of Istanbul from the UNESCO list of World Heritage sites. The top level of cables was changed from 63 to 55 m (207 to 180 ft), and later in July 2011, it was further lowered to 47 m (154 ft). This revised design was approved in February 2012.
