Noting that the bridge will be constructed as part of the "3rd Strait Bridge and North Marmara Transit Highway Project", Turhan said they are planning to hold a tender for the project in September at the latest. Turhan said the third bridge will be 1,300 meters long and the connecting highway will extend about 300 kilometers. Meanwhile the total cost of the project is estimated at USD 4 billion. He added that the project is envisioned to be completed within five years. Turhan said the railway on the bridge will also be connected to Marmaray.
