The Old Golden Horn Bridge was built in 1974 and it formed part of a long-distance expressway network connecting Asia and Europe. At the same time, it played an important role in connecting the old city and new city of Istanbul. Increased traffic volume and vehicle weight caused damage on the members of the bridge and made them vulnerable against the expected earthquake in the Marmara region. 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 and beams, replacement of the elastomer bearing, installation of a falling-down prevention device and a transverse displacement restriction device, replacement of expansion joint and the expansion of pier foundations.
