The Osman Gazi Bridge aka İzmit Bay Bridge (Turkish: İzmit Körfez Köprüsü) is the fourth-longest suspension bridge in the world, which is located at the Gulf of İzmit along the eastern end of the Sea of Marmara. Marmatek installed four individual vibration monitoring systems on the bridge piers and catwalk of the bridge. Each system includes a high sensitivity two axis accelerometer and a dedicated high resolution datalogger which works 24/7. We are honored to support the construction and engineering team of this mega construction.
