The İzmit Bay Bridge (Turkish: İzmit Körfez Köprüsü) is a suspension bridge located at the eastern end of the Sea of Marmara, close to İzmit and approximately 50 km (31 mi) southeast of Istanbul, Turkey. It will be one of the longest suspension bridges in the world by the length of central span.
Construction and operation of the bridge was awarded to a joint venture formed by five Turkish companies (Nurol, Özaltın, Makyol, Yüksel and Gocay) and one Italian construction company Astaldi following the international Build–operate–transfer tender that took place in April 2009.[3] As of 2010 the contract was signed for the project that is estimated to cost 
11 billion for the entire highway from Gebze to Bursa. The construction is expected to be completed in 2017.[4]
On March 30, 2013, Prime minister Recep Tayyip Erdoğan laid the groundstone for the bridge.[5]
Design
The US$1 billion privately financed bridge, designed by Danish architecture firm Dissing+Weitling,[4] will connect the northeastern and southeastern coast of the Izmit Bay, significantly reducing regional travel time. Crossing the bay, the bridge and the connecting highway will provide three lanes of traffic in each direction.
The most important dimensions are:[4][6]
- total length: 2,682 m (8,799 ft)
- main span length: 1,550 m (5,090 ft)
- side spans length: 566 m (1,857 ft)
- clearance: 64 m (210 ft)
- tower height: 234.4 m (769 ft)
- tower size (at the base): 8 m × 7 m (26 ft × 23 ft)
- deck size: 30.10 m × 4.75 m (98.8 ft × 15.6 ft)
The bridge will be fourth longest suspension bridge in the world.[7]
