It opened in 2020. 1915 is part of the name. "The name of the bridge symbolizes the Canakkale Naval Victory of March 18, 1915. It is painted red and white to represent the Turkish flag." It is built over the Dardanelles Strait. The cost of the project is $3.41b. It is the second tallest bridge in Turkey. [TheConstructor] At 322m (1,056'), the Sultan Selim Bridge is the tallest in Turkey, but it is a cable-stayed bridge.

With a total length of 4,608 m (almost 3 miles), 3,563 m (2.2 miles) anchor to anchor and 2,023 m (1.3 miles) from pylon to pylon and a height of 318 m, it was the longest and tallest suspension bridge when opened in 2020. It is definitely the world's longest pylon to pylon. I don't know if it is the longest anchor to anchor. It is certainly not the longest bridge with a suspension span. I doubt if it is the longest anchor to anchor because some sources (e.g. 1915canakkale) claim "longest mid-span suspension bridge in the world." Adding the adjective "mid-span" implies that it is the 1.3 mile span that breaks a world record.
"The deck of the bridge is 72.8 metres [239'] high and has a total width of 45.06 metres [148']." [trtworld]

The ferry crossing ranged from 1.5 to 5 hours. The span length of 2,023 is "meant to commemorate 2023 as Turkey’s 100-year anniversary after the dissolution of the Ottoman Empire." The tower's height of 318m remembers the Mar 18, 1915, date of the naval battle. This source quotes a cost of $2.7b. (This cost may be for the bridge alone and the $3.4b above may includes the roads that are needed so that it would not be a bridge to nowhere.) [popsci]

Highway Engineering Discoveries posted The longest suspension bridge. It spans 2,023 meters and is open to traffic over the Dardanelles waterway. Kevin Fransen: This is partially inaccurate and misleading. Yes, the longest span is 2,023 meters (6,637 feet). But the total length is only 4,608 meters (15,118 feet). The Mackinac Bridge isn’t even the world’s longest suspension bridge. And it’s total length is 8,038 meters (26,372 feet). Highway Engineering Discoveries posted again |

The European side is anchored on shore. But the Asian side is anchored on reclaimed land. So we can see the huge concrete blocks that are needed to hold the cables.

| roadtraffic-technology The deck supports 3 lanes of traffic with no shoulder and two walkways. But the walkways are for maintenance workers. "The structure of the bridge will be a reinforced concrete deck, which will be supported by two shear-connected longitudinal steel box beams that will be interconnected through steel crossbeams supported on external cantilevers." |

| BridgeWeb, Photo supplied by Limak The side spans are 770m with approach viaducts of 365m and 680m. "An orthotropic steel deck with twin box girder sections was chosen for its high wind resistance. The tower foundations stand on the seabed at -45m on the Asian shore and at -37m on the European shore. As part of the soil improvement works, 165 steel piles of 2.5m diameter were driven for the Asian tower foundation, and 203 for the European tower’s foundation." |

Meriaura’s vessel Aura is also spending the summer supporting the project in the Çanakkale Strait, transporting 89 components to the construction site. Offshore operations are then performed in using the vessel’s dynamic positioning capabilities, with the ship’s involvement in the project lasting until the end of August 2021." |
