In the late sixteenth century, the scholar Wang Xigun watched seasonal floods choke the salt trade across Yunnan’s Luoci River. He funded three stone arches, naming the crossing the Feihong Bridge. His son, Wang Ziyi, later completed the work. This path carried heavy, coarse blocks of salt from the Heijing wells toward Kunming. In 1672, a salt official named Guo Yanbi replaced the stone with a covered wooden corridor. Floods claimed that structure, and a devastating torrent in 1871 swept away its successor. For twenty years, local officials embezzled the salt tax funds meant for repairs. Finally, in 1891, Zou Xingde of the Heijing Administration secured a loan from the provincial treasury to rebuild the crossing.

The bridge completed in March 1892 is the red sandstone structure standing today. It stretches 92 meters from north to south, supported by four thick piers that divide the river into five unequal arches. The builders used lime mortar to seal the heavy red blocks. They carved a rough-scaled dragon’s head on the eastern side of the central arch and a dragon’s tail on the western side, a symbolic plea for the beast to pacify the waters. At the northern entrance, a stone gate tower rises five and a half meters, its three-tiered eaves sheltering five stone steles. Two of these tablets preserve the names of the construction committee, while another bears the name "Fengyu Bridge," a title celebrating abundant salt and rich taxes.

Human hands have left deep marks on this stone. Generations of pack mules and salt carriers wore down the flat deck. At the southern end, stone elephants kneel in quiet vigil, their trunks weathered smooth by centuries of passing hands. At the northern end, stone lions stand guard. In 1958, workers demolished the southern wooden pavilion, and in 2008, a modern highway bridge diverted vehicular traffic. Today, the bridge serves local pedestrians. The red sandstone blocks, scarred by runaway vehicles and softened by wind, remain a quiet monument to the ancient salt route.
