These viaducts were as important as the bridge itself since they connect the bridge to the No.1 Peripheral Road. Built in 1973, these viaducts had also suffered the corrosive effects of time and therefore need to be retrofitted. The reinforcement project was finished in 2008 and now these viaducts are capable of withstanding the earthquake which is expected to take place in a few decades. 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 installation of a falling-down prevention device, replacement of the elastomer bearing, replacement of an expansion joint and the replacement of bearings.
