French bridge master Dr. Michel Virlogeux expressed that the 3rd Bosphorus Bridge will be a unique structure in many terms. Proslulý francouzský mostař Dr. Michel Virlogeux řekl, že 3rd Bosphorus Bridge bude unikátní konstrukcí v mnoha ohledech. Highlighting the weight of the bridge, he said: “This bridge has to hold big loads due to the fact that there is a railway on it. In addition to this, the regular loading wil be extremly high, as a result of the heavy traffic in Istanbul. There are regular suspended cables and stiffening cables – which are stretched out with direct connection to the tower – in the design of the bridge. This is an extraordinary system for the purpose of the combined road/railway traffic. Similar bridges were built in the 19th century, but they did not have the same style. The 3rd Bosphorus Bridge has been developed with this philosophy from the beginning using all the actual capacity we have with modern computering. We can call it a hybrid structure. This adds additional feature to the bridge”. S poukázáním na hmotnost mostu uvedl: „Tento most musí být schopen přenášet velká zatížení vzhledem k tomu, že je na něm umístěna železniční trať. Kromě toho bude následkem husté dopravy v Istanbulu extrémně vysoké i běžné zatížení. V návrhu mostu jsou zakomponována standardní visutá lana a ztužující lana – která jsou v přímém spojení s pylony. Tento jedinečný systém byl vytvořen kvůli kombinaci silniční a železniční dopravy. Podobné mosty byly stavěny již v 19. století, ale neměly stejné technické řešení. Dr. Michel Virlogeux stated that the bridge is the most important bridge project in the world, which is under construction at the moment. He also gave assurance to the dwellers of Istanbul on the matter of earthquake performance, he explained this by saying: “Earthquake is a big question mark in Turkey. Thankfully, the Bosphorus Region is more secure seismically when compared to the İzmit shoreline. It is at a level of one-third of the İzmit shoreline. Our bridge was designed in a way that it will not be affected by any earthquake thanks to its flexibility”. Dr. Michel Virlogeux also drew attention to the fact that the international characteristics of the project are very important in terms of experience stating: “We increased our experience and quality with the fact that people from all around the world come and work here.... It is a major advantage that talents and expe
