Daelim Completes the Main Towers of Turkey’s Canakkale Bridge


Upon completion of the bridge, Canakkale Bridge will be the longest suspension bridge in the world


Daelim and SK E&C successfully completed construction of the main towers of Canakkale Bridge, the world’s longest suspension bridge, on June 14. It has been one year since the foundation of the tower (caissons) was installed. The height of the main tower increases as the distance between the main towers is longer in a suspension bridge connecting the main towers with cables and fastening the top plates on the vertically hung down steel wires from the cables. The distance between the main towers of Canakkale Bridge will be 2,023m with total bridge length of 3,600m, and the tower will be the world’s highest steel-frame main tower at 334m high when the bridge is completed compared to France’s Eiffel Tower (320m) and Japan’s Tokyo Tower (333m).
The weight of the blocks ranges from 195 tons to 850 tons.
The main towers were installed by laying hollow quadrangle box-shaped steel plate blocks. Because the tower becomes thinner as it goes up, the lower width of a main tower installed on the foundation is 11m, and the width at the highest spot is 8m. One main tower consists of 64 blocks and weighs a whopping 18,000 tons. After completing the main towers, the site plans to install cables connecting the main towers as the core process in constructing a suspension bridge.
