The most important part of the Orhangazi-İzmir highway project is the towers rising above the sea, which form the bridge legs in the construction of the Izmir Bay Crossing Bridge.

In the construction of the Izmir Bay Crossing Bridge, the most important part of the Orhangazi Izmir highway project, the towers rising above the sea, which form the bridge abutments, have been completed. The tower height of the 4th largest bridge in the world is 254 meters. The two collars come together for the first time as the guide cable starts to be drawn for the main cable that will carry the decks where the vehicles will pass. The main cable will consist of 330 thousand meters of thin cable when its assembly is completed. Following the completion of the main cable, the laying of the decks will begin next May. The bridge is scheduled to be completed by the end of this year.

254 METALLIC TOWERS ON THE SEA COMPLETED

The Gebze-Orhangazi-İzmir (Including İzmit Bay Crossing and Connection Roads) Motorway Project, which was tendered by the General Directorate of Highways with the Build-Operate-Transfer model, covers 384 kilometers, including 49 kilometers of highway and 433 kilometers of connection roads. In the project where work continues on a total of 12 reinforced concrete viaducts, 2 in the Gebze-Orhangazi-Bursa section and 14 in the Kemalpaşa Junction-İzmir section, 6 viaducts between Gebze and Bursa were completed.

One of the most important pillars of this project, the construction of the İzmit Bay Crossing Bridge, continues uninterruptedly. The production of bridge towers, which started to be manufactured in July 38, on caisson foundations weighing 404 tons, which were immersed in the sea after being manufactured on land, has been completed. Unlike similar bridges in Turkey, the bridge towers, which were manufactured in steel in Gemlik and brought to the construction site, reached 2014 meters in height, were made by welding 254 steel blocks to each other. It was stated that each of these parts weighed between 88 tons and 350 tons.

TWO COLORS COMBIN WITH CABLE CABLE BEFORE BEFORE

After the completion of the bridge towers, work was started for laying the main cable between the two sides. The main cable for the main cable that will carry the grid is carried out with great care. The guide cable pulled by private tugboats is pulled under the sea before along the bridge line. After the guide cable reaches the opposite shore, the cranes on the 254 meter giant bridge towers will be lifted. Meanwhile, it was stated that the Gulf of Izmit will be closed to the traffic of the ship.

TABLETS WILL BE STARTED IN MAY

After the completion of the guide cable, the main cable will be moved between the two collars, which will carry the vehicles where the vehicles will cross. The main cable consists of a total of 330 thousand meters of thin wire. The main cable to be installed by a robot acting on the guide cable is expected to be completed in February. In May, 2015 will begin laying the first boards.

THE WORLD'S 4.BUYUK BRIDGE WILL BE

It is stated that the middle span of the bridge, which is planned to be 2 thousand 682 meters in total, will be 1500 meters and it will be the fourth bridge with the largest middle span in the world. When the bridge is finished, it will serve as 3 lanes, 3 departures and 6 arrivals. The bridge will also have a service lane. While 1350 people are currently working at the construction site, the works continue for 24 hours. When the Gulf Crossing bridge is completed, the current time of passing the gulf from 70 minutes by circumnavigating the bay and an hour by ferry will be reduced to an average of 6 minutes. The cost of crossing the Izmit Bay Crossing Bridge, which was built with an investment of 1.1 billion dollars, will be 35 dollars plus VAT.
