Luoyang Bridge, China’s earliest stone beam bridge built in the seaport, spans the Luoyang River from south to north in the southern suburb of Quanzhou... Luoyang Bridge was built from 1053 and was completed in 1059... Built from light grey granite, the bridge resembles a silver dragon lying above the green water. The bridge features ship-like piers and a unique method of oyster consolidation. The ship-like piers could easily cut the rapid current in the river. Thousands of oysters were bred around the footstones and piers so that their secretions would act as kind of cement. This was the world’s first example of the use of biology in bridge building and shows the great wisdom of the ancient Chinese people.

“Some of the mightiest and most impressive Roman Bridges, which fall broadly into two groups, are to be found in Spain.

As a contrast there is themajestic majestic lofty bridge of few and unequal arches thrown across a wide rocky gorge (H. Shirley 21).”
