Chongqing Yangtze Bridge Opened To Traffic Is Significant (figure) - Chaotianmen Bridge, Chaotianmen

As to improve the important transport of Chongqing Road and Bridge Link project

, Yangtze Bridge is completed, will achieve with the Chongqing suburbs smooth trunk road connection, network interaction, expansion of Chongqing's economy, "artery" to drive the overall economy of Chongqing synchronization development.

Last four years of construction, known as the "world's first bridge," the Chongqing Yangtze Bridge on April 29 opened to traffic.

Festival, tens of thousands of people every day play on the Yangtze Bridge

After the opening of the Chongqing Yangtze Bridge, grand, magnificent, lying on the river's "Red China" the main arch, is like a beautiful rainbow, become the most beautiful bridge in Chongqing, but also a beautiful mountain city landmark.

The world's first bridge built in Chongqing Yangtze Bridge

Chongqing Yangtze Bridge is the first time, China Communications Construction Company Limited BT model to construct the first project, the headquarters is located in Wuhan, China Communications Bureau is responsible for the construction of two aircraft. Junction of the Yangtze River and Jialing River Bridge is located, the "gateway to the first mountain the Yangtze River Bridge" in the world. Bridge length 1741 m, with a total investment of over 3.0 billion. Three-span continuous bridge design in the steel truss arch bridge, main span 552 m, than the world famous Sydney Harbour Bridge, Australia's main arch span much longer, is the world's largest arch bridge span. Bridge modeling using the "door of the century" design philosophy, and the shape of Sydney Harbour Bridge. Upstream road bridge, pass under the light Track Two-tier design, making it China's largest rail bridge at the public. Bridge bridgehead north and south sides of each of the two pairs together is just a "Jiefangbei" look. Portal in Chongqing Chaotianmen River, 552 m span steel truss arch will be two "Jiefangbei" high lift, as it constitutes a magnificent Chongqing beautiful landscape.

Bureau of the project, according to two

Air Chief Engineer Wang book about survival, build long-span steel arch bridge, the biggest difficulty is the bridge without external support force, carrying capacity, thanks to the mechanical design of steel arch their accuracy. 552 m span steel truss arch bridge steel truss structure, the installation of the upper, Yangtze Bridge is the most characteristic and most technical difficulty of the key construction process. In addition, the entire bridge to reach 50 thousand tons of steel, compared with Beijing's National Stadium "Bird Nest" more than the amount of steel, and its service life up to 100 years.

Experts said that in ordinary view, Yangtze Bridge Arch has a "look", but if the mechanics from the professional point of view, it is a three-span continuous girder bridge, the bridge construction process, the need to streamline beam, cantilever beam, continuous beam, cable-stayed system, and arch thrust, no thrust arch ... ... covering almost all of the bridge construction methods, the complex and frequently change the system is full of risks and challenges, it is very rare in China.

As to improve the important transport of Chongqing Road and Bridge Link project, Yangtze Bridge is completed, will achieve with the Chongqing suburbs smooth trunk road connection, network interaction, expansion of Chongqing's economy, "artery" to drive the overall economy of Chongqing synchronization development.
