The Mecidiyeköy Viaduct in Türkiye is located on the “Circular Road,” Highway E-5, one of the busiest routes for traffic flow in both Istanbul and the nation. This road serves as a critical link for emergency vehicles and relief teams during earthquakes and other natural disasters.

Services provided included quality control, project management, construction supervision, and the adaptation of design and erection documents to meet local standards. The work involved steel jacketing of the piers, reinforcement of RC linings at the pier bottoms, and the installation of damping devices, such as isolation bearings, on the pier tops.
