The Osman Gazi Bridge (Turkish: Osmangazi Köprüsü) is a suspension bridge spanning the Gulf of İzmit at its narrowest point, 2,620 m (8,600 ft). 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 then-longest suspension bridge in Turkey and the fourth-longest (ninth-longest as of 2025) suspension bridge in the world by the length of its central span.
The length of the bridge was surpassed by the Çanakkale 1915 Bridge across the Dardanelles strait, which became the longest suspension bridge in the world when it was opened on 18 March 2022.
