Being that they protect the people’s lives and property, as well as the functions of the City of Istanbul as both the country’s economic center and the “bridge” between the West and the East, the approach viaducts of the New Golden Horn Bridge had as much importance as other large scale bridges. For this reason, the viaducts were retrofitted as the others and were not expected to be out of service in case of a major earthquake. Services provided by Miyamoto Turkey included quality control, project management, construction supervision services, the rearrangement of design and erection documents according to local conditions for reinforcement of piers, installation of a falling-down prevention device and the expansion of pier foundations.
