The exposed stakes have an average height of about 2m and an average diameter of 40cm. There are pine, cypress, fir, mulberry and precious nanmu, and the bridge deck no longer exists.
The excavated site of the ancient bridge is a relatively concentrated part of the bridge piles, and there are still 30 meters outside the main hall, which has been buried and protected.
During the archaeological excavation, the site of Bridge 2 was discovered 300 meters east of Bridge 1.

It is a large wooden bridge in Qin and Han Dynasties in China.
