You don't need to know anything about building or engineering to admire a structure like Shuiduhe Bridge. Stop for a moment and take in the workmanship and design on display.
Shuiduhe Bridge is an interesting place to begin your discovery of Changsha. This modern structure is recommended by fellow travelers, but it isn't the only thing to do here. Pencil in time for other sights like Changsha Window of the World, Tangren Cemetery, and Laodao River to get a complete picture of what's on offer in the area.
