Zhen'an Bridge, Wooden beam bridge in Linjiang, Pucheng County, China

Zhen'an Bridge is a wooden beam bridge over the Linjiang Creek, a tributary of the Nanpu Creek, in Linjiang town, Pucheng County, Fujian. It has four stone piers and three openings; round logs laid in a well pattern form the corbelled arches, with large timber beams resting on top. The bridge is 70.45 m long and 3.6 m wide, and a 3.5 m high covered gallery stands on the deck.

Zhen'an Bridge was first built in 1379, the twelfth year of the Ming Hongwu era, and was originally called Linjiang Bridge. It was renamed Zhen'an Bridge in 1446, the eleventh year of the Zhengtong era. It was rebuilt several times, in 1529, 1648, 1910 and 1936, and was listed as a county-level cultural relic in 1982 and a provincial-level one in 2005.

The name changed from Linjiang Bridge to Zhen'an Bridge in 1446, during the Zhengtong era. The covered gallery on the deck, 3.5 metres high, shelters people crossing in bad weather. The bridge was listed as a county-level protected site in 1982 and a provincial one in 2005.

You can walk across the bridge and observe the construction details up close from inside the passage. It helps to move slowly to fully appreciate the stonework and craftsmanship.

The bridge's arches are not true vaults: round logs were stacked in a criss-cross, well-shaped pattern on the stone piers, and long timber beams were laid flat on top. The four piers are stone masonry, while the rest of the 70.45-metre structure is timber.
