Osmangazi Bridge

The Osmangazi Bridge extends 2,682 meters across the Gulf of İzmit with a main span of 1,550 meters and towers standing 252 meters high.

The bridge was officially opened on June 30, 2016, after construction that began in March 2013 by a Turkish consortium including Nurol and Makyol.

The structure represents Turkey's modern engineering achievements and serves as a symbol of technological progress connecting Europe and Asia via the Marmara region.

The bridge operates as a toll road on the O-5 motorway with six traffic lanes and reduces travel time between Istanbul and İzmir by approximately one hour.

Turkish motorcycle champion Kenan Sofuoğlu rode across the bridge before its opening, reaching a record speed of 400 kilometers per hour on his Kawasaki motorcycle.
