Yangtou Bridge (formerly jiefang bridge) in Fu 'an City was built in the mid-1960s. It was originally a highway bridge on the Zhuyang Line (that is, the former station Sanjiaoping to Yangtou Highway). Up to now, the service life of the bridge has exceeded 40 years. After decades of wind and rain erosion, the bridge has been seriously damaged due to floods caused by typhoons. Although the bridge has been restricted at present, there are still great security risks. In 20 10, Fuan city decided to rebuild the bridge, but considering the traffic pressure and other issues, it was not completed until 20 12. The new bridge will be built on the original site. The reconstructed Han Yang Bridge has a total length of126.08m and a width of 26m, including sidewalks, non-motor vehicle lanes and motor vehicle lanes. According to the standard design of urban (Grade III) main roads, the calculated driving speed is 30 kilometers per hour. The total investment of the project is19,363,200 yuan. Compared with the old bridge, the new bridge has fewer piers in water, stronger flood discharge capacity, appropriate height, reasonable longitudinal slope, higher driving comfort and no maintenance.
