brief introduction
Yangzhong, as an important part of Zhenjiang, is closely connected with Zhenjiang urban area and new district, with huge traffic demand and increasingly high requirements for timeliness and comfort. But for a long time, Yangzhong and Zhenjiang can only rely on the old provincial highway 238 with large traffic volume, and the traffic efficiency is not high. According to Ding Feng, director of the Municipal Transportation Bureau, although Jingang Avenue (to the new section) has been successfully implemented, only one bridge can be reused to communicate with Yangzhong after this road reaches the Dayao line of the county road, and its fast-track advantage has not been fully exerted. There is also the bottleneck of Jiajiang Bridge in Yangzhong West, and the connection between Yangzhong City and Jingang Avenue is very inconvenient.
History of bridge construction
Yangzhong Yangtze River Bridge No.1 is a bridge funded by the local government of Yangzhong City, with a total length of1172m and a width of15m. There are 30 piers and abutments with a total investment of 654.38+52 million yuan. The bridge was officially started in May, 65,438+0994. The completion of Yangzhong Yangtze River Bridge ended the history that Yangzhong Island in Jiangsu was connected with the outside world without a bridge.
The total investment of the Second Yangtze River Bridge in Yangzhong is 220 million yuan, of which the approach road is 6.5 kilometers long, including the bridge length 176 1 m, the bridge width 17 m, the maximum span 120 m and the clear navigation height 18 m.. The structural form is a common beam bridge. Yangzhong Yangtze River Bridge 2 connects Yangzhong main island and the affiliated island of Xilaiqiao Town. After it was completed and opened to traffic, the distance between Yangzhong and Shanghai and Suzhou and Xichang was shortened by 30 minutes, which created favorable conditions for Yangzhong to further accept the economic radiation from Shanghai and southern Jiangsu.
The construction of the third bridge
The third Yangzhong Bridge under construction is located 3 kilometers downstream of the first Yangzhong Bridge. It consists of three parts: north wiring, Jiajiang Bridge and south wiring. The whole line adopts the first-class highway standard and urban expressway standard, with six lanes in both directions and a design speed of100 km/h. The project starts at the intersection of Jingang Avenue and Dayao Line in Zhenjiang New District, crosses Jiajiang of the Yangtze River and ends at the intersection of Outer Ring South Road and Zhongdian Avenue. The total length of the route is 6.036 kilometers, and the width of the north-south connecting subgrade is 46.5 meters; Jiajiang Bridge is 2.503 kilometers long. The main bridge will adopt a continuous beam bridge scheme of 75+4×125+75m, with a deck width of 34.5m, six lanes in both directions and auxiliary roads. The estimated investment of the project is 936 million yuan, including 570 million yuan for Jiajiang Bridge. The project was completed and opened to traffic on October 28th, 20 14/KLOC-0.
At the groundbreaking ceremony, Chen Jianshe, deputy mayor, said that the construction of the third bridge in Yangzhong will speed up the docking between Yangzhong and Zhenjiang, realize the formation of a half-hour metropolitan area from Yangzhong to Zhenjiang, help Yangzhong truly enter the Ning, Zhen and Yang plates, and connect with the Yangtze River Delta, which will have a significant and far-reaching impact on accelerating the construction of a new riverside city in Yangzhong and the development of riverside eco-tourism.
