How many bridges have been built on the Yongjiang River in Nanning? What is the difference? Thank god, help me.

At present, there are 10 bridges widely known.

1. Yongjiang Bridge (Bridge 1)

2. Zhongxing Bridge (Second Bridge):

3. Baisha Bridge (Third Bridge)

4. Qingchuan Bridge (Fourth Bridge):

5. Yonghe Bridge (Fifth Bridge)

6. Hulu Ding Qiao

7. Nanning Bridge (also known as Qingshan Bridge)

8. Lingtie Bridge

9. Nanning Taoyuan Bridge:

10. Nanning Beida Bridge:

Nanning Yongjiang Bridge is the first reinforced concrete cantilever box bridge with a main span of 55 meters designed according to the closed thin-walled bar theory of the Soviet Union, which has special significance. The total length of the bridge is 394.6 meters, with a single cantilever beam, with a span of 45 meters at both ends and 55 meters in the middle. A 23-meter mid-suspended beam double cantilever bridge is adopted, and the piers are double columns. The bridge was designed by Guangxi Communications Department and completed by Liuzhou Railway Bureau and Shanghai Tongji University.

Yongjiang Bridge, located in the urban transportation hub, has become the most convenient and fast river-crossing bridge connecting Jiangbei District and Jiangnan District of Nanning. There is a huge flow of people and vehicles every day. After years of full use, cracks appear in the bridge to varying degrees. It is understood that this comprehensive "physical examination" covers more than a dozen projects. Experts will use advanced instruments such as ultrasonic instruments and microscopes to conduct a comprehensive analysis of the bridge. For example, concrete ultrasonic instrument, concrete rebound instrument and other instruments can detect the thickness of concrete, and the steel bar corrosion tester can determine whether the steel bars in concrete are corroded and the degree of corrosion. Through comprehensive data collection and combination calculation, we can get the relevant data such as the stress condition and actual bearing capacity of the bridge.
