Excerpt from Wikipedia

The Çanakkale 1915 Bridge (Turkish: 1915 Çanakkale Köprüsü), also known as the Dardanelles Bridge (Turkish: Çanakkale Boğaz Köprüsü), is a suspension bridge being constructed in the Province of Çanakkale in northwestern Turkey. Situated just south of the towns of Lapseki and Gelibolu, the bridge will span the Dardanelles strait, about 10 km (6.2 mi) south of the Sea of Marmara.

The bridge is the centerpiece of a planned 321 km (199 mi) long US$2.8 billion Kınalı-Balıkesir Motorway, which will connect the O-3 and O-7 motorways in East Thrace to the O-5 motorway in Anatolia. With a main span of 2,023 m (6,637 ft), the bridge will surpass the Akashi Kaikyō Bridge in Japan by 32 m (105 ft) to become the longest suspension bridge in the world.


The total length of the bridge is planned at 3,563 m (11,690 ft) and together with the approach viaducts the length reaches 4,608 m (15,118 ft), which will surpass the total length of the Osman Gazi Bridge and its approach viaducts by 527 m (1,729 ft) to become the longest bridge of any type in Turkey.

The total height of the bridge's two towers will be 318 m (1,043 ft) tall, making it the second tallest bridge in Turkey, after the Yavuz Sultan Selim Bridge, and the third tallest structure in the country. Internationally, the bridge will become the sixth tallest bridge in the world, surpassing the Sutong Bridge in China. The deck of the bridge will be at 72.8 m (239 ft) high and have a total width of 45.06 m (147.8 ft) and a maximum thickness of 3.5 m (11 ft). The deck will carry six lanes (three in each direction) of motorway, together with two walkways on each side for maintenance.


On 16 May 2020, the second tower was completed, on the side of Gallipoli (European coast).

As of 13 November 2021, all block decks have been achieved.

Symbolic figures

Some symbolic figures are associated with the bridge. The number 1915 in the name, the height of the towers (318 m), and the groundbreaking date (March 18) are related to the Turkish Naval Victory on March 18, 1915 during the naval operations in the Gallipoli Campaign. The length of the bridge's main span, 2023 meters, refers to the centennial of the Turkish Republic in 2023.
