Introduction to Yongan Bridge: Located not far to the west of Chantan, it is a stone bridge across the Xixi River. It was built in the 28th year of Daoguang reign of the Qing Dynasty, more than 160 years ago. The bridge body is 73 meters long and 2 meters wide, with a total of 17 holes and 16 groups of pier stones. Each group has three groups of standing stones. There is one horizontal strip stone on the base and 5 straight paving stones in each group. The bridge deck has a total of 80 paving stones. . On each pier, a protective pier stone is erected 2 meters away from the pier. The local people call it "Stone General" to reduce the impact of floating objects on the bridge. A stone dam is also built more than 10 meters downstream of the bridge. A row of anchor steps (qin bridge) is built on top to slow down the flow speed and protect the bridge and bridge foundation. The design is very scientific.
There is a Juxian Pavilion at the northwest end of Yong'an Bridge. In the pavilion are engraved inscriptions on the process of building the bridge, the first stonemason who built the bridge, the name of the donor who built the bridge, and the amount of silver and many other cultural materials. The unique and antique Juxian Pavilion is not only an organic part of Yongan Bridge, but also a simple and quiet scenery of Xipu Village.
