The Su Causeway is the longest series of bridges crossing over Hangzhou's West Lake. The causeway is named after the Song Dynasty poet, Su Dong Po, who was also the governor of Hangzhou. The causeway runs across the lake from Nanping Road, to the "lotus in the Breeze Quyuan Garden".

The causeway consists of six simple yet beautiful bridges and the embankments along the way are all planted up with pretty trees and flowers. In the evenings, the causeway is illuminated by green lights and this is a favorite place for Chinese couples to promenade, holding hands and declaring their undying love! This is a lovely example of typical Chinese design and the style is beautifully delicate and refined.
