Second Bosphorus bridge or the Bridge Fatih Sultan Mehmet is the second suspension bridge over the Bosphorus. The bridge connects the district to the Roumeli Hisari that in the European part and Anadolu Hisari in the Asian part of Istanbul. It was built near the fortresses of Rumeli, Chisari and Anadoluhisari that in 1985-1988, he controlled the Bosphorus.

The bridge is named in honor of the Sultan of the Ottoman Empire Mehmed Fatih the Conqueror, who opened Constantinople in 1453. It was designed by Freeman Fox & Partners, an international consortium, which had previously developed the Bosphorus bridge.

The structure is located behind the defensive fortress of the XV century Rumeli Hisari, closer to the Black sea, crosses the Bosphorus Strait and is a 5 kilometers North of the First Bosporskogo bridge. The construction of the bridge Fatih Sultan Mehmet began in 1985 and ended in 1988. His discovery, which took place on 29 may 1988, was also awarded one of jubilee and commemorative dates in Turkish history is 535 years since the conquest by Sultan Fatih Mehmed the city of Constantinople.

It is also known that the Second Bosphorus bridge was erected on the same place for almost two and a half thousand years before it was located first pontoon bridge of Darius the king.

This bridge, though built by the Japanese builders in the same constructive manner as that of the First Bosphorus bridge, representing the hanging fabric and the stretch between the pylons on the ropes, using the same material (steel), is a more powerful structure, which surpasses its predecessor (both the main span and the costs of its construction). The length of the bridge is about 1510 meters. The length of the main span of 1090 meters long and 39 meters, and the height of the towers is 165 meters above the water level. The distance from the roadway to the surface water is 64 meters. The bridge became famous as one of the largest bridges takes up the length of the twelfth place in the world. Its construction took about 130 million US$.

For the construction of the bridge Fatih Sultan Mehmet designing his engineers to invent new design solutions and materials, and used has long been used in America and Europe, a system of steel cable-stayed bridges. The pylons of bridges, sharply vzryvayuscheysya over the water and echoing from minaret towers located on the shores of the Bosphorus mosques, and modern radio and towers, attach steel parts brand new sound. Therefore, we can safely say that not only the transport function of the bridges over the Bosphorus, but also well-matched form connects the East and West, Europe and Asia.

The main structure of the bridge was made of flexible cables, chains and ropes, which are in tension, while the roadway remains suspended. In its construction were used ropes and wire cables are composed of high-strength steel, the tensile strength of which is 2 to 2, 5 GN/m2 (200 to 250 kgf/mm2). This significantly lowers the own weight of the bridge and allows you to cover large spans. However, he has a low rigidity because due to the movement of the temporary load on the bridge cable or chain changes its geometric shape and cause large deflections of the superstructure. In order to reduce the deflections of the bridge was reinforced by longitudinal beams and trusses stiffness at the level of the roadway. This contributed to the temporal distribution of the load and reduce the deformation of the cable.

Second Bosphorus bridge is not a pedestrian. It is a high-speed rapid transit system, the fare for which the fee is charged. Daily passes through about one hundred and fifty thousand units of vehicles carrying more than five hundred thousand passengers. Pedestrian walkway on the bridge was closed due to the fact that he tried many times to use to commit suicide.
