The Fatih Sultan Mehmet Bridge or Second Bosphorus Bridge (Turkish: Fatih Sultan Mehmet Köprüsü, short FSM, or İkinci Boğaziçi Köprüsü ), named after Sultan Mehmed II, is the second bridge in Istanbul which spans the Bosphorus and so the European connects to the Asian part of the city. It was opened in 1988 and is located about five kilometers north of the Bosphorus Bridge ( Boğaz Köprüsü ) of 1973. The lying as part of the motorway O -2 and released only to motor vehicles bridge is adjacent to the inner-city traffic as a link in the motorway connection from Edirne to Ankara.
Description
The Fatih Sultan Mehmet Bridge is a suspension bridge with four lanes separated by a median strip and both sides of a footpath. The flat section of the bridge deck connects situated on the high banks neighborhoods, the neighborhoods close to the river deep below the bridge. They crossed the Bosporus with a clear height of 64 m, so that can happen even large ships such as aircraft carriers and cruise ships.
Unlike the first Bosphorus bridge their pylons are not on the shores of the Bosphorus, but on top of the high bank. As leading to the highway bridge extends on both sides to the pylons, there are outside of the pylons any spans, but only about 210 m in each case to the mounting blocks of the pylons supporting the tensioned cable.
The entire length of the building of anchor block to anchor block is measured 1510 m. The span between the pylons is 1090 m. The Fatih Sultan Mehmet Bridge has therefore longer by 16 m bridge deck as the first Bosphorus bridge, but does not require a long outer spans.
Even their steel pylons have no foundation except the foundations. You just start on the high banks below the bridge deck and are therefore ( including the feet in the concrete bases ) only 111.1 m high. Stand out from the road surface to 98.2 m. Similar to the first Bosphorus bridge the two stems of the pylons are connected by a cross bar halfway up from the ground and by a between the tips and stiffened.
The bridge deck consists, as in the first Bosphorus Bridge, from an aerodynamically shaped, flat hollow box made of steel sheets whose shape has been tested in the wind tunnel to provide the wind little resistance and based on his profile to avoid vibrations and aeroelastic flutter.
The bridge deck is a total of 39.4 m wide and only 3 m high. It has a 30.8 m wide flat top, which turns on both edges with a 1.5 m wide slope in the slightly deeper 2.8 m wide footpaths. The flat, only 23.8 m wide underside of the box girder is connected to the outer edges by a long incline. Therefore, the footpaths act similar to an upside-down wing.
The support cables are made, as with all large suspension bridges made of parallel wire cables. Unlike the first Bosphorus Bridge, the planners have again used the usual vertical hangers.
History
The Fatih Sultan Mehmet Bridge was designed by Freeman Fox & Partners, who had already planned the first Bosphorus Bridge and in the meantime, the Humber Bridge. The Turkish engineering firm BOTEK Bosphorus Technical Consulting Corp.. was also involved in the planning and construction supervision.
The Fatih Sultan Mehmet Bridge was built by a consortium of three Japanese, an Italian and a Turkish company ( Ishikawajima - Harima Heavy Industries, Mitsubishi Heavy Industries, Nippon Kokan, Impregilo and STFA ). The groundbreaking ceremony was completed on 29 May 1985. The construction cost of the overall project Kınalı - SAKARYA HIGHWAY, which included the bridge, were 130 million U.S. dollars. It was officially traveled for the first time by the then Prime Minister Turgut Özal on 3 July 1988 during the opening ceremony.
Toll
The Fatih Sultan Mehmet Bridge is a toll road. From 2004, a payment by the radio receiver is only possible to pay with cash was abolished as well as the occupied people with toll booths.
