The
1915 Canakkale Bridge
(
Turkish
:
1915 Canakkale Koprusu
) is a road
suspension bridge
in the province of
Canakkale
in northwestern
Turkey
. Situated just south of the coastal towns of
Lapseki
and
Gelibolu
, the bridge spans the
Dardanelles
, about 10 km (6.2 mi) south of the
Sea of Marmara
.
[2]
The bridge was officially opened by
President
Recep Tayyip Erdo?an
on 18 March 2022 after roughly five years of construction.
[4]
The year "1915" in the official Turkish name honours an important Ottoman victory against firstly a naval engagement followed by a land invasion on the Gallipoli peninsular by the forces of Australia, New Zealand (The ANZACS), France and The United Kingdom from the 25th April 1915 which were largely evacuated by December of that year.
The bridge is the
longest suspension bridge in the world
?with a main
span
of 2,023 m (2.023 km; 1.257 mi), the bridge surpasses the
Akashi Kaikyo Bridge
(1998) in Japan by 32 m (105 ft).
[5]
[6]
[7]
It is the centrepiece of the planned 321-kilometre long (199 mi)
US$2.8 billion
O-6
motorway, which will connect the
O-3
and
O-7
motorways in
East Thrace
to the
O-5
motorway in
Anatolia
.
[8]
The bridge is the first
fixed crossing
over the Dardanelles
[9]
and the sixth one across the
Turkish Straits
, after three bridges over the
Bosphorus
and two tunnels under it.
[10]
Design and cost
[
edit
]
The bridge's tender project was designed by
Tekfen Construction and Installation
and detailed designed by
COWI A/S
[11]
and Pyunghwa Engineering Consultants (PEC) in South Korea (for cable design and approach bridge design packages only).
Arup
and
Aas-Jakobsen
participated in the project as Independent Design Verifier (IDV). The Administrator consultants are Tekfen
[12]
and T-ingenierie.
The total length of the bridge is 3,563 m (11,690 ft) and together with the approach viaducts the length reaches 4,608 m (15,118 ft), which surpasses 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.
[13]
The height of the bridge's two towers is 334 m (1,096 ft),
[note 1]
making it the tallest bridge in Turkey, surpassing
Yavuz Sultan Selim Bridge
, and the third tallest structure in the country. Internationally, the bridge is the
second tallest bridge in the world
, surpassing the
Pingtang Bridge
in China. The deck of the bridge is 72.8 m (239 ft) high and 45.06 m (147.8 ft) wide, with a maximum thickness of 3.5 m (11 ft). The deck carries six lanes of motorway (three in each direction), together with a walkway on each side for maintenance.
[13]
According to
President Erdo?an
, the bridge cost 2.5 billion euros (2.7 billion US dollars) to build, but would save €415 million ($458 million) per year from a reduction of fuel consumption and carbon emissions.
[14]
History
[
edit
]
Proposals for a bridge spanning the
Dardanelles Strait
[15]
have existed since the 1990s. A bridge was proposed again in 2012, and in 2014, it was placed in the Turkish government's future transportation projects list.
[16]
In September 2016, the government officially launched the bridge building project.
[16]
Bids for the contract to construct the bridge were made in 2017.
[17]
The contract was awarded to a consortium containing Turkish companies
Limak Holding
and
Yapı Merkezi
, alongside South Korean companies
DL Holdings
and
SK Ecoplant
.
[18]
Construction began in March 2017.
[19]
The bridge was initially scheduled for completion in September 2023,
[18]
and later brought forward to March 2022.
[19]
On 16 May 2020, the second tower was completed, on the
Gallipoli
side (European coast).
[20]
By 13 November 2021 all block decks were installed.
[4]
The toll bridge opened for traffic on 18 March 2022, with a toll price of 200
lira
(€6.78).
[14]
A Chinese consul general
Zhang Meifang
uploaded a video to social media on 13 Feb 2023 that inaccurately claimed the bridge in Turkey withstood the
recent devastating earthquake
thanks to Chinese technology. Zhang wrote, "The bridge built by China in Turkey’s withstood the earthquake #ChinaTech." She also falsely claimed that "a subsidiary of Shudao Group is the sole participant in the construction." The bridge was also unlikely to be in any danger from the devastating magnitude 7.8 earthquake that struck Turkey's southeastern provinces on 6 Feb 2023, as it is located approximately 950 kilometers (590 miles) northwest from Kahramanmara?, the city closest to the quake's epicenter.
[21]
Symbolism
[
edit
]
Some symbolic figures are associated with the bridge:
- the number 1915 in the name,
- the height of intersection point of main cable (318 m),
[22]
- and the opening date (18 March),
are all related to the date of
the Ottoman naval victory
, on 18 March 1915, during the naval operations in the
Gallipoli campaign
.
Meanwhile, the length of the bridge's main span (2,023 metres) refers to the
centennial
of the Turkish Republic (1923?2023).
