3. The Legs of the Bosphorus Bridge Passed 90 Meter: 3 which will be one of the world's leading bridges under construction with high engineering and technology. The Bosphorus Bridge and North Marmara Motorway continue to work in full swing. The work carried out by the Dogan News Agency (DHA) team on the European side of the 24 watch shift system, the length of the bridge on both sides of the bridge crossed the 90 meter.
President Abdullah Gül, President of the Grand National Assembly of Turkey Cemil Çiçek and Prime Minister Recep Tayyip Erdoğan's participation in 29 May 2013'de Garipçe Village of Sarıyer and Beykoz Poyrazköy located between the 3. The construction of the Bosphorus Bridge and the Northern Marmara Motorway (between Odayeri-Paşaköy and the connection roads) and the viaducts on the Asian and European sides continue uninterruptedly.
Foreign engineers, including the Japanese, are also found on the construction site where the majority of Turkish engineers work. A continuous work of concrete is produced on the bridges where a feverish work is exhibited and the 2-3 meter is increased daily. 65 workers are working on a tower foot. The length of the feet on both sides of the bridge has passed the 90 meter.
North Marmara Motorway (including 3. Bosphorus Bridge) Odayeri-Paşaköy (including 3. Bosphorus Bridge) was contracted with Build-Operate-Transfer model and a contract was signed on 15 May 2013. 3 included in the project. Bosphorus (Yavuz Sultan Selim) Bridge is planned to be completed and opened to traffic in 2015 year.
3. The Bosphorus Bridge is the world's longest and the world's tallest tower with 58.4 m tower height.
In the statement made by the General Directorate of Highways, the following information about the 3rd Bosphorus Bridge was also included:
“Istanbul, which is the largest city in our country, has a great density in terms of traffic due to the fact that both daily urban travels and transcontinental transits are provided by roads of 87%. 600 cars equivalent pass through the Bosphorus and FSM Bridges, which bear the burden of road transport between Asia and Europe, which is 2,5 times the planned capacity of the bridges. During the day, the traffic hours on the bridge are increasing and the crossing times are found due to the vehicle queues in the ring roads that provide access to the bridges. Simultaneous loss of time and fuel, interruption of transit freight transport, and economic and social negative consequences of the drivers' journeys becoming frustrated. In addition, over-capacity traffic transports cause shortening of the service life of the existing Bosphorus bridges.
In addition to all these data, data such as population, per capita car and number of trips are evaluated in line with the projections. The need for a third bridge over the Bosphorus is clearly evident. Based on this need, it is possible to reduce the traffic density in Istanbul's urban and existing Bosphorus bridges, ensure that the vehicles are continuously, safely and comfortably switched, and to ensure the transit of the trucks carrying transit cargo without entering the inner city traffic. The construction of the Northern Marmara Motorway, including the 3. Bosphorus Bridge, which includes the railway crossing, was decided.
When deciding on the bridge crossing and highway routes, the green areas are identified with the corridor to minimize damage, and the route is equipped with tunnels and viaducts to minimize the damage to the nature. 5 times the number of trees remaining on the route will be planted in the areas to be shown by the Regional Directorate of Forestry in the next 3 years and there will also be an ecological bridge on the route to ensure that wildlife is not interrupted. ”
