One pair of dragon s bridges lies and builds the Lu river 3 kilometers west of the waterside town and collapses to wash on the river, because two rivers zigzag like the dragon, so gain the name, is commonly called as seventeen-arch bridge ,It is one and three pavilion large 17 hole stone arch bridges, 148 meters long, 3-8 meters wide, it is one of the famous historic sites in Yunnan Province, considered to be highest porous multi-arched bridge of artistic value of the largest scale of Yunnan Province, have already listed in China and built the history of bridge.
Mao Yisheng, famous bridge expert of China, came and investigated, classified it as one of the large-scale ancient bridges of China in 1965, then is determined as the Key Cultural Relic Unit under State Protection of Yunnan Province. One pair of dragon s bridges was established in Qianlong Year of Qing Dynasty (1736- 1795),Just build three holes of stone bridge, later, because the river of Shanghai, collapsing towards the river to overflow in the river of Shanghai at that time, the riverbed is widened gradually, in the solitary river of small three hole bridge, can t traverse two sides, the local officer the people are in 19 years (1981) for a line of light Continue 14 hole, join end to end with three hole bridge that build originally, wild goose tooth continued to hold, united, so also called The seventeen-arch bridge . Unless it is high in bridge 9 meters, three hole and 5 meter wide when first building, and then to build is 14 hole and 3 meter wide,bridge 148 meter long, body of a bridges the whole with typing and digging about 500 stone that be levelled very much inlaying to build but, it is columns to build the strip stone on both sides. There are three pavilions on the bridge, and then all destroy among salty bumper harvest year in the flames of war. The 24th year of Guangxu (1898) Rebuild three and fly in the eaves type attic again, more powerful than the ones that built originally.

The top floor builds three for a principal column of a hall small buildings, present mountain Shape is arranged, carry the eaves to resolve into product three of the word have a rest the mountain is carried small. Take advantage of a situation to carry small in four pieces of dislocated upwarping four corners on the second floor. Whole the intersection of pavilion and the intersection of shelf and layers of stoplog, fly to the intersection of eaves and interlock, carved beams and painted rafter, novel and unique.
Go on the stone arch bridge, no matter from which angle appreciates a pavilion in the middle of the bridge, will all be marvellous endlessly, really there are eaves in the floor, chisel and carve exquisitely, too beautiful to be absorbed all at once outside building, eaves in this attic. The west end floor pavilion of the bridge is two storeys, the layers of eaves collect together pinnacles, reflect with the middle high building. The floor pavilion of the east has already been destroyed. One pair of dragon s bridges breaks out in level land of 5 kilometers, it seems that Changhong poaches the wave. It has adopted the characteristic of the Chinese bridge architectural style, combines architecture science of the bridge and plastic arts together, condensing people s superb technology and clever intelligence in the southern regions of the Yunan Province, its scale of building and artistic value are very few in China.
