The Osmangazi Bridge is a suspension bridge spanning the Gulf of İzmit at its narrowest point, 2,620 m. The bridge links the Turkish city of Gebze to the Yalova Province and carries the O-5 motorway across the gulf.
The bridge was opened on 1 July 2016 to become the longest suspension bridge in Turkey and the fourth-longest suspension bridge in the world by the length of its central span.
The length of the bridge is expected to be surpassed by the Çanakkale 1915 Bridge, under construction across the Dardanelles strait, and will become the longest suspension bridge in the world upon completion scheduled for 2022.
