Baiyun Bridge, Stone arch bridge in Luting Township, Yuyao, China

Baiyun Bridge is a steep-arch single-span stone bridge over the Xiaolu Stream in Zhongcun Qianshan Natural Village, Luting Township. Built of irregular and block stones on a rock face, it has a deck 3.8 m wide, an arch rise of 6.6 m and a span of 12.65 m, with an arch exceeding a half-circle to about two-thirds of a circle. The south side has 48 steps and the north side 30, and the deck is flanked by 18 railing panels and 16 posts.

Baiyun Bridge was first built in the Zhenguan period of the Tang dynasty and is one of three Tang-era bridges still on their original site in Ningbo. The present structure dates from the 16th year of the Guangxu reign (1890). It served as the boundary bridge between old Yuyao County and old Yin County, and was listed as a Zhejiang provincial cultural relic on 7 January 2011.

The bridge's name comes from a couplet carved on its east side: "White water spans the rainbow waist, the road runs north and south; Cloud village keeps the moon's shadow, the boundary draws Zheng and Yu." A local legend says a stonemason built the arch so its reflection would form a moon and keep the golden ox of Niushan from leaving. The Song poet Lou Yue and the Ming poet Wang Xigun wrote poems about the bridge, and the 2016 horror film Baiyun Bridge was shot here.

The bridge is easy to reach year-round and requires no entrance fee for visitors. It is best to visit during daylight hours so you can see the details of the structure and the village surroundings clearly.

At the shallow water by the south end, a row of stepping stones (dingbu) joins the bridge, letting pedestrians cross the stream on foot; the arrangement also shortens the arch span and helps the bridge discharge floodwater. The arch board at the top is carved with the name Baiyun Bridge and the date Guangxu Gengyin (1890).
