The West Causeway of the Summer Palace is located in the western part of the garden. It was built by Emperor Qianlong, modeled after the Six Bridges of the Su Causeway in Hangzhou. From north to south, the six bridges are Jiehu Bridge, Binfeng Bridge, Yudai Bridge, Jingqiao Bridge, Lianqiao Bridge, and Liuqiao Bridge. Each bridge has its own unique design, blending the essence of northern and southern garden art. Yudai Bridge is the most eye-catching. Its single-arch, high-arched white marble bridge has a clear span of 11.38 meters and a flowing curve. Large vessels can pass through it, and a boat barge is located on the west side of the bridge.
It is a prime example of a classical Chinese stone arch bridge and the only intact original Qianlong structure to survive after 1860. The other five bridges were destroyed, and the current bridges are reconstructions. Standing on the six bridges, you can see the Wuquanshan Pagoda clearly, as if it were right inside the garden.
To reach the Six Bridges of the West Causeway, you can take a boat from the east bank of Kunming Lake or from the Dragon King Temple Pier to Yudai Bridge. Alternatively, you can reach it by land from the marble barge, heading south from Jiehu Bridge. Visitors to the Summer Palace should not forget to walk along the West Causeway!
