The last bridge deck for the İzmit Bay Bridge, which will make it the suspension bridge with the fourth largest main span, will be installed Thursday at a ceremony attended by President Recep Tayyip Erdoğan and Prime Minister Ahmet Davutoğlu.
The bridge is the biggest part of the Gebze-Orhangazi-İzmir Highway Project which will shorten the distance between Istanbul and İzmir by roughly 140 kilometers, bypassing the long-stretching Gulf of İzmit. Constructed under the "build-operate-transfer model," the Gebze-Orhangazi-İzmir Highway (including the İzmit Bay Bridge) will be 433 kilometers long and will include 384 kilometers of highway and 49 kilometers of access road.
The project begins with an interchange (2x5 lanes) that will be built 2.5 kilometers after the Gebze Interchange on the Anadolu Highway, and ending at the Otogar Intersection on the İzmir Highway. The bridge will reach a height of 252 meters and the bridge deck will be 25.93 meters long, with a main span length of 1,550 meters. Totaling 2,682 meters, the İzmit Bay Bridge will have the fourth largest main span in the world. Ninety-nine percent of the north and south anchorage blocks of the bridge are complete. The installment of the bridge is planned to be completed at the end of April and the bridge is expected to be opened to traffic at the end of May, following isolation and asphalt application.
