Luoyang Bridge was a transportation hub connecting Quanzhou to northern Fuzhou and the nation’s vast heartland. Luoyang Bridge, Anping Bridge and Shunji Bridge link up a convenient coastal trunk road. It was a pioneering project and a significant historical milestone in the development of Quanzhou’s water-land transportation network. It is a classic example of large-scale infrastructure facilities whose construction was led by the government and involved the concerted efforts of the entire society. It reflects the efforts of all segments of society, including officials and monks, to facilitate and contribute to commercial and trade activities. Luoyang Bridge is situated at the mouth of the Luoyang River about 10 kilometers northeast of Quanzhou City. Originally known as Wan’an Bridge, its construction began in 1053 and was completed in 1059. Running northeast to southwest, the extant bridge is about 731 meters long and 4.5 meters wide. It has 47 spans and 45 piers and passes a small natural island in the middle of the river. The stone beams of the bridge are boulder strips of a considerable size. There are balusters and guardrails on both sides of the bridge deck. The construction used the methods of“raft-shaped foundations”“reinforcing the foundation by cultivating oysters” and “transporting heavy stone slabs by using buoyancy forces and waves”, accumulating a wealth of precious technical experience for the subsequent bridge-building boom in Quanzhou. On both sides of the bridge, there are seven stone towers in various shapes from the Song Dynasty, as well as four stone statues of generals providing divine protection for the bridge. On the islet stand the Central Pavilion and the Stele Pavilion with the inscription “Western River, Sweet Rain”. On the southern end of the bridge is a temple dedicated to Cai Xiang, who was credited with building the bridge. On the northern end of the bridge is Zhaohui Temple from the Song Dynasty, which is dedicated to King Tongyuan; the temple used to be the command center for Cai Xiang when he was directing the bridge construction. Luoyang Bridge was included into the third group of major cultural heritage sites protected at the national level by the State Council in January, 1988.
