Discovered in China a wooden bridge 2,000 years believed to be the world's largest


The Qin Dynasty was the most powerful in the early history of imperial China, which saw the realization of many important projects, including the Great Wall and the mausoleum of Qin.

Their capital was near the modern city of Xi'an (Shaanxi provincial capital), also home of the famous Terracotta Warriors and near where Chinese archaeologists recently found buried a wooden bridge 300 meters long and about 20 meters wide, believed to be the largest of the known world at that time.

The bridge could go back to the Qin Dynasty (221-206 BC), when crossing the Wei River, the largest tributary of the Yellow River, joining two imperial palaces of the ancient capital. The archaeological site occupied by the bridge was first discovered in April, when some farmers found huge piles of wood on their farms when they made earthworks.

An initial investigation revealed that the largest pillar subsequently found was 9 feet long and held a board measuring 18.5 meters wide. Archaeologists also found large pieces of stone used to build these wooden pillars.

Is the first time found a wooden bridge of this size and age, which is a great find for the study of ancient architecture and transport so distant time.

Archaeologists also found a "twin bridge" contemporary, but smaller, about 200 meters west of the big bridge. And it is believed that the two bridges continued to be operated in the last Han Dynasty (202 BC-220 AD), with the largest become a transportation artery for the strength in Chang'an, the capital of the empire after the overthrow of the Qin dynasty.
