Location: Istanbul, Türkiye
Client: IHI Corporation
Scale: 152 and 90.7 m long, 11 and 5 m wide, precast I-beam girder viaducts

As they protect lives, property, and the functions of Istanbul, the country’s economic center and a “bridge” between the West and East, the approach viaducts of the New Golden Horn Bridge are as important as other large-scale bridges. For this reason, the viaducts were retrofitted like the others and are not expected to be out of service in the event of a major earthquake.

Services provided included quality control, project management, construction supervision, and the adaptation of design and erection documents to local conditions. The work involved reinforcing piers, installing a falling-down prevention device, and expanding the pier foundations.
