The bridge is expected to be built at a cost of around 2 billion USD. Another 0.8 billion USD covers the cost of the motorway. The ground-breaking Ceremony took place on 18 th March 2017. Opening of the bridge is planned in 2022, in advance of the centenary anniversary of the declaration of the Republic of Turkey in 1923. The General Directorate of Highways (KGM) awarded the 1915 Çanakkale Bridge and Highway Project within the framework of a Public Private Partnership model to the consortium, which subsequently established a joint-venture company (Commissioned Company), Çanakkale Otoyol Köprüsü İnşaat Yatırım İşletme A.Ş. (Çanakkale Motorway Bridge Construction Investment Management Inc.). GENERAL DESIGN The main structure will be 3-span steel suspension bridge.
