白沙大桥, Stone arch bridge in Jiande, China.

The Baisha Bridge is a stone arch bridge of 362 m length and 24 m height over the Xin'an River, downstream of the Xin'an River hydroelectric station, linking Mayuan on the north bank with Baisha village on the south. It has five piers and six main arches: the two central spans measure 50 m and the four side spans 45 m, each main arch flanked by three smaller arches. The roadway is 7 m wide with 1.5 m walkways on both sides.

The Baisha Bridge was built between October 1959 and July 1960, connecting Mayuan on the north bank with Baisha village on the south bank of the Xin'an River, downstream of the Xin'an River hydroelectric station. It was China's first multi-span, large-span stone arch bridge, and in 2011 it was listed as a Zhejiang Provincial Cultural Relic Protection Unit.

The bridge's name was written by Guo Moruo, the poet and historian, whose calligraphy marks the structure. Visitors can spot the pair of large stone lions at each end of the bridge and count the 260 small lions carved along the railings, a local detail that ties the crossing to stone-carving tradition.

Access to the bridge is straightforward for both pedestrians and vehicles without special requirements. The surface is solid, but it is advisable to walk with care when wet since stone can become slippery.

The bridge carries 260 small stone lions on its railings, plus a pair of large lions at each end, and its name was written by the poet and historian Guo Moruo. It was completed on 1 July 1960 as China's first multi-span, large-span stone arch bridge.
