A zig-zag bridge is a pedestrian bridge composed of short segments, each set at an angle relative to its neighbors and usually with an alternating right and left turn required when traveling across the bridge. It is used in standard crossings for structural stability; and in traditional and contemporary Asian and Western landscape design across water gardens.
When constructed of wood, each segment is formed from planks and is supported by posts. When constructed of stone, the bridge will use short or long rectilinear slabs set upon stone footings.

Standard bridge
The post and plank version has an advantage when employed as a crossing of a muddy bottom or marsh: It is structurally stable, where a straight bridge might tend to tip due to the posts moving in the soft mud. Each segment of walkway mutually supports the next from twisting and tipping by being securely fastened to it. This is the same advantage possessed by a zig-zag split rail fence.
