Chongqing is known as the bridge capital, and Egongyan Bridge is a very distinctive and magnificent bridge. Because this bridge is the main road connecting the east and west of the main city of Chongqing, with eight lanes in both directions, it is still not out of date. The Xiejiawan Interchange nearby has therefore become an important transportation hub in the main urban area of Chongqing.
Egongyan is a fairly flat place, which used to be farmland. During the War of Resistance against Japanese Aggression period, the National Government established an arsenal here to produce bullets. Because of the land acquisition, most local residents moved to Yangjiaping, forming a new street named Hexing Road, and the word "Crane" was written on the street, meaning that people who moved from Hegaoyan must be richer.
After liberation, the factory was renamed as a construction factory, which is one of the two military-level enterprises in Chongqing (the other is Chongqing Iron and Steel), and its status and scale can be imagined.
During the Anti-Japanese War, the take-off airport was built in Jiulongpo, and the Fo (Tuguan) Jiu (Longpo) highway was built, which connected the airport with the city traffic and facilitated the traffic in Egongyan area. There is a street called Xiejiawan on Egongyan, which was cut off by the construction factory, so the name of Egongyan gradually disappeared, and people called that area Xiejiawan. There is a dormitory building of a construction factory in Xiejiawan. Because it is built along the highway and is arc-shaped, it is called arc-shaped building. Some people think that Xiejiawan is named after that building, but it is not.
With the development of the city, Yangjiaping, located in the western suburbs, has become an important sub-center of Chongqing, and Xiejiawan, which is adjacent to it, has become the "fat meat" in the eyes of the government and businessmen. In this case, the construction factory will be moved soon, and the large flat land will be vacated for commercial development. Thinking about the mysterious factories that will be razed to the ground and replaced by high-rise buildings also gives birth to some quite complicated feelings.
But Egong Rock is still there, and chengdu-chongqing railway passes under it. It's just that the Jiubin Road under construction has filled the riverside, making Yan Na look less majestic. Of course, there are no more cranes dancing under rocks in Yan Na, but there is more noise and excitement. The Egongyan Bridge on the Yangtze River in Chongqing started construction in 19971February, with a total investment of 14. 1 100 million yuan. The total length of the bridge is 7.27km, in which the main bridge is1420m, the main bridge is1022m and the main span is 600m. The bridge type is a double-tower portal suspension bridge with the main tower height 163.9 meters. The towering gateway twin towers have become another major landscape in Chongqing. It was completed and opened to traffic in 2000.
The bridge is a two-way six-lane expressway with a deck width of 35.5 meters, a design speed of 80 kilometers per hour and a daily traffic capacity of 65,000 vehicles.
For the first time in China, the new technology of construction cableway traction was adopted in the erection of main cable strands of this bridge, which created a record of no broken wires and broken wires in the erection of main cables in China. In addition, according to the characteristics of large fluctuation of river water level and disordered water flow, the bridge pioneered the new technology of hoisting and installing steel box beams in the air by aerial ropeway in the world.
Recently, many happy events have taken place in the road and bridge construction in Chongqing. The Chang (Shou)-Fu (Ling) Expressway was officially opened to traffic on the 27th, and the construction of Liang (Ping), Chang (Shou) and Yu (Shui) expressways also started on the 27th.
Chongqing Yangtze River Egongyan Bridge project is a part of the east-west main road in the expressway system in the main city. It starts from Chengdu-Chongqing Expressway in the west, exits the Grand Mansion in Jiulongpo District, crosses the Yangtze River via Xiejiawan, passes through Chongqing Economic and Technological Development Zone, and connects with Chongqing-Guizhou Expressway in the east.
The total investment of the Egongyan Bridge on the Yangtze River in Chongqing is one of the practical things that the Chongqing Municipal Government has promised to do for the citizens. The project started in 19971February, and the total investment is estimated to be 14. 1 100 million yuan. The total length of the bridge is 7.27km, in which the main bridge is1420m, the main bridge is1022m and the main span is 600m. The bridge type is a double-tower portal suspension bridge with the main tower height 163.9 meters. The towering gateway twin towers have become another major landscape in Chongqing.

Gan Yuping, vice mayor of Chongqing, said at today's opening ceremony that Egongyan Bridge, which connects Jiulongpo District, Nan 'an District, Economic Development Zone and High-tech Development Zone in Chongqing, will play an important role in improving the traffic network structure of Chongqing and promoting the social and economic development of Chongqing and the west.
