2. What is the design heritage?Prominent in traditional Asian and Western landscape architecture, particularly water gardens
3. Why do zig-zag bridges wobble and turn?The angled segments spread the weight across many parts of the bridge. This helps the bridge resist wind and earthquakes and keeps it stable.
4. How do wooden and stone zig-zag bridges differ?Wooden bridges use planks and posts, giving a natural, rustic look. Stone bridges use cut slabs on stone footings, making them strong and more solid.
