Usually, we officially call the surging eastward-flowing river formed by the confluence of the Jinsha River and the Minjiang River in Yibin City, Sichuan Province, the Yangtze River. Before the founding of New China, there was no bridge on the Yangtze River and the only way to cross the Yangtze River was by ferry, making transportation very inconvenient. After the founding of New China, at the end of 1954, the Wuhan Yangtze River Bridge, the first bridge over the Yangtze River in thousands of miles, was built. After the reform and opening up, especially since 1995, with the diversification of construction funding sources (originally they were all state appropriations, and no bridge tolls were collected after construction; now they are various forms of financing and loans, and loans are repaid after construction) and With the rapid development of bridge-building technology, a large number of high-investment, high-tech, and long-span Yangtze River bridges have sprung up like mushrooms after a rain. As of March 28, 2005, the Yibin-Shanghai section of the Yangtze River has been completed and opened to traffic. 41 bridges, 18 bridges under construction (including tunnels, excluding bridges under planning or design). There are ***46 bridges built or under construction along the Jinsha River, Tongtian River, and Tuotuo River upstream of the Yangtze River (due to the small scale of bridge construction in the reaches above the Jinsha River and the small demand for funds, the province, Municipal and county-level local governments may have their own bridge construction plans, and it is difficult to make accurate statistics. Therefore, bridges that are under design or planning but have not officially started construction are not included.) For details, see How Much Do You Know about Yangtze River Bridges (2). Therefore, there are 105 bridges on the Yangtze River and its main source Jinsha River, Tongtian River, and Tuotuo River (including tunnels, ^0^)! There are 15 cross-river passages in the Yangtze River section from Shanghai to Yibin that are planned or designed but have not yet been officially started: Beijing-Shanghai High-Speed ??Railway Nanjing Yangtze River Bridge, Nanjing Fourth Yangtze River Bridge, Nanjing Fifth Yangtze River Bridge, Ma'anshan Yangtze River Bridge, Wuhu Second Yangtze River Bridge, Wangjiang Yangtze River Bridge, Jiujiang Second Yangtze River Bridge, Jingyue Yangtze River Bridge, Chibi Yangtze River Bridge, Wanzhou Third Yangtze River Bridge, Fengdu Yangtze River Second Bridge, Changshou Yangtze River Bridge (road bridge), Chongqing Yuzui Yangtze River Bridge, Chongqing Cuntan Yangtze River Bridge (Railway Bridge), Jiangjin Guanyinyan Yangtze River Bridge. There are 59 Yangtze River bridges (including the Yangtze River Tunnel) in the section of the Yangtze River from Shanghai to Yibin. From upstream, they are: 1 bridge between Shanghai and Jiangsu Province: Chongming Cross-River Channel (under construction) 7 bridges in Jiangsu Province: Sutong Bridge (under construction), Jiangyin Yangtze River Bridge, Yangzhong Yangtze River Bridge (note: does not span the north and south of the Yangtze River), Runyang Yangtze River Bridge, Nanjing Yangtze River Second Bridge, Nanjing Yangtze River Bridge (dual use for road and railway), Nanjing Yangtze River Third Bridge (under construction built); 3 within Anhui Province: Wuhu Yangtze River Bridge (dual-purpose for highway and railway), Tongling Yangtze River Bridge, and Anqing Yangtze River Bridge; 1 bridge between Jiangxi and Hubei Province: Jiujiang Yangtze River Bridge (dual-purpose for highway and railway); within Hubei Province 17 (including tunnels): Huangshi Yangtze River Bridge, Hubei-Huang Yangtze River Bridge, Wuhan Yangluo Yangtze River Bridge (under construction), Wuhan Tianxingzhou Yangtze River Bridge (road and railway dual-use) (under construction), Wuhan Second Yangtze River Bridge, Wuhan Yangtze River Bridge Tunnel (under construction), Wuhan Yangtze River Bridge (dual use for road and railway), Wuhan Baishazhou Yangtze River Bridge, Wuhan Junshan Yangtze River Bridge, Jingzhou Yangtze River Bridge, Zhicheng Yangtze River Bridge (dual use for road and railway), Yichang Yangtze River Bridge, Yichang Yangtze River Railway Bridges (railway bridges) (under construction), Gezhouba Sanjiang Bridge, Yiling Yangtze River Bridge, Xiling Yangtze River Bridge, Badong Yangtze River Bridge; 24 in Chongqing: Wushan Yangtze River Bridge, Fengjie Yangtze River Bridge (under construction), Yunyang Yangtze River Bridge , Wanzhou Second Yangtze River Bridge, Wanyi Railway Wanzhou Yangtze River Bridge (railway bridge) (under construction), Wanzhou Yangtze River Bridge, Zhongxian Yangtze River Bridge, Shizhong Expressway Zhongxian Yangtze River Bridge (under construction), Fengdu Yangtze River Bridge, Fuling Lidu Yangtze River Bridge (under construction), Fuling Yangtze River Bridge, Fuling Shibangou Yangtze River Bridge (under construction), Chongqing-Huaihua Railway Changshou Yangtze River Bridge (railway bridge), Chongqing Dafo Temple Bridge, Chongqing Chaotianmen Yangtze River Bridge (under construction), Chongqing Yangtze River Bridge , Chongqing Caiyuanba Yangtze River Bridge (under construction), Chongqing Egongyan Bridge, Chongqing Lijiatuo Bridge, Chongqing Yudong Yangtze River Bridge (under construction), Chongqing Masangxi Bridge, Baishatuo Bridge (railway bridge), Diwei Yangtze River Bridge, Jiangjin Yangtze River Bridges; 6 bridges in Sichuan Province: Luzhou Tai'an Yangtze River Bridge (under construction), Luzhou Railway Yangtze River Bridge (railway bridge), Luzhou Second Yangtze River Bridge, Lu Yangtze River Bridge, Jiang'an Yangtze River Bridge (under construction), Yibin Yangtze River Bridge (under construction) ); ★ The idea of ??constructing Chongming Cross-River Tunnel was formally proposed in 1993. After 10 years of discussions, in February 2003, the Chongming Cross-River Tunnel Project Proposal was finally approved by the State Council.

In mid-August 2004, the feasibility study report of the Chongming Cross-River Channel Project was officially approved by the Development and Reform Commission of the State Council. The project includes the Shanghai Yangtze River Tunnel, Shanghai Yangtze River Bridge, Chongqi Bridge, Chonghai Bridge and related connection roads (see diagram), with a total investment of 12.3 billion yuan. It is a national key highway construction plan determined by the Ministry of Transport in Shanghai - An important part of Xi'an Highway. It is connected to Wuhaogou in Pudong District of Shanghai (east line) and Luojing in Baoshan District (west line) to the south, via Changxing Island and Chongming Island, to Haimen City and Qidong City in Jiangsu Province to the north, and to the Ningtong-Qidong Expressway in Jiangsu Province. Connected by road. The east line will be implemented first, and its direction is: Pudong No. 5 Ditch - Changxing Island - Chongming Chenjia Town - Chongming Link Expressway - Chongming Niupeng Port - Jiangsu Haimen Qinglong Port - Jiangsu Ningtongqi Expressway, The total length is about 106 kilometers. On December 28, 2004, the foundation stone laying of the Shanghai Yangtze River Tunnel and Shanghai Yangtze River Bridge on the east line was officially launched. On August 30, 2005, a bank loan of 7.616 billion yuan was obtained. From then on, the progress of the project will be greatly accelerated. The Shanghai Yangtze River Tunnel is 8.95 kilometers long. It starts from the Pudong Wuhaogou Suburban Ring Road (Far East Avenue-Wuzhou Avenue) interchange, passes through the Nangang waters, lands at the Xinkai River on Changxing Island, and connects to the Panyuan Highway interchange on Changxing Island. The length of the circular shield section of the tunnel is 6.97 kilometers. The tunnel is arranged with six lanes in both directions. A transverse passage is freely set up every 1.2 kilometers between the two circular tunnels, and there are 4 transverse passages. The diameter of the tunnel shield is 15.2 meters. The world's largest diameter shield tunnel. The Shanghai Yangtze River Bridge is 10.27 kilometers long, starting from the north shore of Changxing Island, crossing the waters of Beigang, landing at Xijiagang on Chongming Island, and connecting to the Chongming-Chenhai Highway interchange. The main navigation hole and auxiliary navigation hole of the bridge are in the form of a cable-stayed bridge, with the main span of the cable-stayed bridge being 670 meters. ★ Sutong Bridge Highway Bridge. The Sutong Bridge under construction connects Suzhou City and Nantong City in Jiangsu Province. It is about 82 kilometers away from the Jiangyin Yangtze River Bridge and 108 kilometers away from the Yangtze River estuary. The total investment is 6.27 billion yuan. It is divided into three major parts: the main bridge and the north-south wiring. Among them, the north bridge The connection is 15.1 kilometers long and ends at Xiaohai, which intersects Tongqi Expressway; the south connection is 9.1 kilometers long and ends at Dongbang, the intersection with Yanjiang Expressway and Sujiahang Expressway; the main bridge is 2088 meters long and the main span of the cable-stayed bridge is 1088 meters, the main span is about 200 meters longer than the Tatara Bridge in Japan, which currently has the largest span in the world. The cable tower of the bridge is 300.4 meters high, making it the tallest bridge tower in the world and nearly 100 meters higher than the existing tallest bridge tower in China. The foundation of the bridge is buried to a depth of 80 meters, with a navigation clearance height of 62 meters. 50,000-ton container ships can pass under the bridge. The designed wind speed of the bridge is 47m/second, which is equivalent to twice that of a Category 12 typhoon. After the bridge is completed, it will become the world's largest span cable-stayed bridge (cable-stayed bridge is one of the various bridge types with the span capacity second only to the suspension bridge). The bridge started construction on June 27, 2003. The pile foundation and cap of the main pier were completed in May 2005. The cable tower construction is currently underway. The bridge is scheduled to be completed and opened to traffic by the end of 2008. ★ Jiangyin Yangtze River Bridge Highway Bridge. The Jiangyin Yangtze River Bridge is the suspension bridge that was “No. 1 in China and No. 4 in the world” (now No. 2 in China and No. 5 in the world) in the 20th century (suspension bridges are the bridges with the largest span capacity. Currently, the bridge with the largest span in the world is the one connecting Japan The Akashi Kaikyo Bridge, the main bridge between Honshu and Shikoku, has a main span of 1,991m and was completed in 1998. The second largest bridge is the Obeli Bridge in Denmark, which is under construction in my country in 1998. The long-span suspension bridge is the Zhoushan Xihoumen Bridge, with a main span of 1,650m, which will rank first in China and second in the world). It is a large highway bridge that crosses the Yangtze River on a national main road. It is the second bridge spanning the north and south of the Yangtze River in Jiangsu Province. The bridge is a cross-river "throat" project for the main national highway from Tongjiang in Heilongjiang to Sanya in Hainan and the national highway from Beijing to Shanghai in the main framework of the "two vertical and two horizontal" highways planned to be built before 2000. It is a national and Jiangsu provincial infrastructure. Key construction projects. Jiangyin Yangtze River Highway Bridge is located between Xishan, Jiangyin City, Jiangsu Province and Shiwei Village, Jingjiang City. The total length of the entire bridge construction is 5.176 kilometers, with a total investment of 3.625 billion yuan.

The total length of the bridge is 3071 meters. The span of the suspension bridge is 369m + 1385m + 309m. The cable tower is 197m high. The diameter of the two main cables is 0.870m. The bridge deck is designed according to the standard of a six-lane highway, with a width of 33.8 meters and a design speed of 100 km/h; the clear navigation height under the bridge is 50 meters, which can meet the navigation requirements of 50,000-ton ships. The bridge started construction on November 22, 1994, and was completed and opened to traffic in September 1999. ★ Yangzhong Yangtze River Bridge Highway Bridge. The Yangzhong Yangtze River Bridge is a bridge built with private funds (funded by the local government of Yangzhong City). It has a total length of 1,172 meters, a width of 15 meters, a total of 30 piers and abutments, and a total investment of 152 million yuan. The bridge officially started construction in May 1992 and was completed and opened to traffic in October 1994. The completion of the Yangzhong Yangtze River Bridge ended the history of Jiangsu Yangzhong Island being connected to the outside world without a bridge. However, the Yangzhong Yangtze River Bridge does not span the north and south of the Yangtze River. It is only a connecting bridge between Yangzhong Island in the Yangtze River and the south bank of the Yangtze River (see the map of Yangzhong City for details). Therefore, I personally think that the bridge is not a true "Yangtze River Bridge" spanning the Yangtze River ( There are many islands in the center of the Yangtze River, some of which are close to the river bank. They can be connected by building a bridge of tens of meters or one or two hundred meters. There is another such bridge in Nanjing, but they obviously cannot be called "Yangtze River Bridges". In the past, many materials regarded Yangzhong Yangtze River Bridge as a typical Yangtze River bridge, so it is still listed here). In September 2002, Yangzhong City started construction of the Second Jiajiang Bridge, also known as the "Yangzhong Second Yangtze River Bridge". It is another connecting bridge between the south bank of the Yangtze River and the island on the east side of the island. The total length of the bridge including the approach road is 6.5 kilometers. The main bridge is 1.755 kilometers long and its structure is an ordinary beam bridge. On October 28, 2004, Yangzhong City held a comprehensive celebration event for the 100th anniversary of the founding of Yangzhong as a county, the 10th anniversary of its establishment as a city, and the completion and opening of the Second Yangtze River Bridge. Since the "Second Yangzhong Yangtze River Bridge" does not cross the Yangtze River and does not cross the main channel of the Yangtze River, it is no longer separately listed as a Yangtze River bridge. ★ Runyang Yangtze River Bridge is the Zhenjiang-Yangtang Yangtze River Highway Bridge, a highway bridge. The Runyang Yangtze River Bridge is an important part of the main framework of Jiangsu Province's "Four Vertical, Four Horizontal and Four Linked" highways and the north-south highway channel across the Yangtze River. It is connected with the main trunk line of the Tongjiang-Sanya National Highway in the north, Shanghai-Nanjing Expressway and 312 National Highway in the south, about 60 kilometers away from the Second Nanjing Yangtze River Bridge in the west, and about 110 kilometers away from the Jiangyin Yangtze River Highway Bridge in the east. The total length of the bridge and the connection between the two sides is about 23 kilometers. It is designed according to the six-lane highway standard. The total investment in the entire project is about 5.3 billion yuan. The project mainly consists of the South Branch Suspension Bridge and the North Branch Cable-Stayed Bridge. The main bridge of the South Branch Bridge is a steel box girder suspension bridge with a cable tower height of 209.9m, a diameter of two main cables of 0.868m, and a span layout of 470m + 1490m + 470m. ; The North Branch Bridge is a steel box girder cable-stayed bridge with main twin towers and double cable planes. The span layout is 175.4m + 406m + 175.4m. The height of the inverted Y-shaped cable tower is 146.9m. It is a steel box girder bridge with cable stays. Face width. The main span of the bridge is 1385m, which is 105m longer than the Jiangyin Yangtze River Bridge. The bridge replaced the Jiangyin Yangtze River Bridge to become the "No. 1 bridge in China" and ranked third in the world. The bridge started construction in October 2000. The main body of the cable-stayed bridge on the north branch was completed in October 2003. The south branch bridge was closed in April 2004 and was officially opened to traffic on April 30, 2005. ★Nanjing Second Yangtze River Bridge Highway Bridge. The Second Nanjing Yangtze River Bridge is located 11 kilometers downstream of the Nanjing Yangtze River Bridge. It consists of the South Branch Bridge, Baguazhou (the third largest island in the Yangtze River) highway connection line, and the "Second Bridge and One Road" of the North Branch Bridge. The total length is 12.517 kilometers. The total investment 3.35 billion yuan. Among them, the Nancha Bridge is a double-tower double-cable-plane steel box girder cable-stayed bridge with a span layout of 58.5m + 246.5m + 628m + 246.5m + 58.5m. With its 628m main span, it has become the longest bridge in the world after the Tatara Bridge in Japan and France. It is the third largest cable-stayed bridge in the world after the Normandy Bridge. The Beichuan Bridge is a prestressed continuous girder bridge with a main span of 165 meters, a bridge length of 2212 meters, and a bridge deck width of 32 meters. The entire line adopts the 6-lane highway standard. The bridge started construction in October 1997 and was completed and opened to traffic in March 2001. ★ Nanjing Yangtze River Bridge is a road and railway bridge.

The Nanjing Yangtze River Bridge is located between Xiaguan and Pukou, Nanjing City, Jiangsu Province. It is the third bridge across the Yangtze River after the Wuhan Yangtze River Bridge and the Chongqing Baishatuo Yangtze River Bridge. It is a super-large railway and highway bridge all designed and constructed by China. It is a double-layer steel-timber beam bridge, with the upper layer being a highway bridge and the lower layer being a double-track railway bridge. The Nanjing Yangtze River Bridge is included in the Guinness Book of World Records as the world's longest road and railway bridge. The main bridge has 10 holes, the railway bridge is 6772 meters long, the highway bridge is 4589 meters long and 15 meters wide. In January 1960, the construction of the Nanjing Yangtze River Bridge officially started. In September 1968, the Nanjing Yangtze River Bridge railway bridge was first completed and opened to traffic; on December 29, the Nanjing Yangtze River Bridge highway bridge was officially completed and opened to traffic. ★Nanjing Third Yangtze River Bridge Highway Bridge. The Third Nanjing Yangtze River Bridge is a key construction project during the National Tenth Five-Year Plan period, with a total length of approximately 15.6 kilometers and an estimated project investment of 2.96 billion yuan. It is one of the five strategic river crossings in Jiangsu Province. The main bridge is a steel box girder cable-stayed bridge with twin towers and double cable planes. The lower beam and the upper part of the cable towers adopt a steel structure, which is the first time in China. The deck pavement of this bridge is the same as that of the Second Nanjing Yangtze River Bridge, using epoxy asphalt. The main span span is 648 meters and is designed as a 6-lane highway. The bridge officially started construction on August 29, 2003 and was closed on May 22, 2005. The bridge is ready to be opened to traffic on October 9, 2005 for the 10th National Games, one year ahead of schedule.
