China News Service, Chongqing, September 1 (Zhang Xu) With the successful hoisting of the last bridge deck, the Chongqing Baijusi Yangtze River Bridge was successfully closed on the 1st.

The bridge is the world's largest span public and rail dual-purpose steel truss cable-stayed bridge, adding another luster to Chongqing's "Bridge Capital" business card.

　　The Baijusi Yangtze River Bridge is a key project in Chongqing. It is jointly invested and constructed by the China Communications Second Navigation Engineering Bureau Co., Ltd. and Chongqing Urban Construction Investment Company.

The bridge has a total length of 1384 meters and a main span of 660 meters. It has been confirmed by Chongqing Municipal Design and Research Institute to be the world's largest span public and rail dual-purpose steel truss cable-stayed bridge.

　　The steel truss girder of the bridge is divided into 93 sections. The standard section is 15 meters long and weighs about 500 tons. It is bolted by 16 rods and 11,000 sets of high-strength bolts.

The steel truss beams are arranged in an inverted trapezoid shape. The upper deck is 38 meters wide, which is an urban expressway crossing the river, and the lower deck is 19.2 meters wide, which is the Chongqing Rail Line 18 crossing river.

The total weight of the steel truss of the bridge is about 44,300 tons, which exceeds the total steel consumption of the "Bird's Nest".

　　According to the Chongqing Municipal Commission of Housing and Urban-Rural Development, the Baijusi Yangtze River Bridge is a control node project across the Yangtze River on the Seven Horizontal Lines of Chongqing City. After the completion of the bridge, it will become an important channel connecting Banan Longzhou Bay area and the Yangtze River Culture and Art Bay area. It is expected to be completed and opened to traffic by the end of this year.

　　A professor from Chongqing Jiaotong University introduced to Zhongfu that Chongqing is divided by the "two rivers and four mountains", and its large mountains and rivers have greatly tested the ability of urban construction workers.

Chongqing's special landforms, high mountains, low valleys, and two rivers have promoted the development of bridge construction.

　　In recent years, Chongqing's bridge construction has developed rapidly, and the total number of bridges has soared from more than 4,000 before being directly under the jurisdiction to more than 10,000. The concept and technical level of bridge construction has jumped into the world's advanced ranks.

Various types of bridges, such as beam bridges, arch bridges, cable-stayed bridges, and suspension bridges, can be found in Chongqing, which is known as the "Bridge Capital".

　　Up to now, a total of 30 river-crossing bridges have been built in the central city of Chongqing.

The downtown area of ​​Chongqing will continue to promote the construction of 13 bridges across the river, including Lijia Jialing River Bridge and Baijusi Yangtze River Bridge.

The Chongqing Municipal Commission of Housing and Urban-Rural Development estimates that by the end of the "14th Five-Year Plan" period, 40 bridges across the river will be basically completed in the central city of Chongqing.
