Zhenhai Bridge, Stone arch bridge in Tunxi District, Huangshan, China

Zhenhai Bridge is a stone arch structure that spans the Heng River with seven arches supporting its length. It directly connects both sides of Tunxi Ancient Street and provides access to the historic merchant quarter in Huangshan.

According to Xiuning County Annals and Huizhou Prefecture Chronicles, the bridge existed before 1490, though local tradition dates it to 1536, the 15th year of the Jiajing reign. It was rebuilt in 1699 under the Kangxi emperor after flood damage. On 7 July 2020 mountain floods destroyed it; salvage work recovered Ming-dynasty stones, and reconstruction finished in December 2021.

The bridge marks the western starting point of Tunxi Ancient Street and serves as a natural gathering point for visitors exploring the historic quarter. It connects two parts of the old merchant district where local commerce and daily foot traffic create a living connection to the past.

The bridge links the west end of Tunxi Ancient Street with Liyang town across the Heng River, at the confluence of the Xin'an and Shuai rivers. Barriers and warning signs at both ends keep motor vehicles off, so the crossing is for pedestrians only. The deck is 133 m long and 15 m wide.

Salvage work in August 2020 recovered the bridge's scattered stone components, including a Ming dynasty baluster post, and exposed the foundations of all six piers before reconstruction began in December 2020.
