Kwan-yin Bridge is a single-arched stone bridge spanning over the Three Gorges and linking the south and the north. Water from the peaks of Lushan Mountain and 99 streams joins into a single, rushing flow that produces big waves and a thunderous sound. The water underneath Kwan-yin Bridge is over 30 to 40 meters deep. The bridge, which leans on the steep cliffs, was built over a gully.

Constructed during the Song Dynasty (960-1279), the Kwan-yin Bridge is 24.4 meters long and 4.10 meters wide. Its roadway is paved with large stones and has stone-carved railings on both sides. The south and north ends of the bridge each have a set of four steps. Paved with seven rectangular granites, the inner arch is solidly constructed and delicately designed. With the exception of the bridge's railings, which were added during the Qing Dynasty (1644-1911), the structure remains unchanged since the Song Dynasty. It can still withstand daily traffic. 

At the south end of the Kwan-yin Bridge is the Sixth Spring under Heaven, and the Kwan-yin Pavilion stands at the north end. Beneath the bridge is the Three Gorges Gully with towering cliffs on both sides. Up along the gully is Yuyuan, a famous scenic spot at Lushan Mountain.

The Kwan-yin Bridge is considered a gem of China's architectural history due to its grand scale, exquisite and solid construction, as well as the arduous efforts that the project demanded.
