A zig-zag bridge has short segments set at an angle to its neighbor and often lacks railings. It is structurally more sound than a straight bridge and forces the walker to slow down and look at the surroundings more closely. However, if you are looking only at the Koi and Siberian iris, it is quite possible to fall off the end into the water. Packaged Recycled PETE Plastic Sleeve with Provenance Card
