Befor giving comment I reccomment you should study more related information and you should respect the other comment from another people too.
Usaully many famous waterfall around the world they also build some facility such as bridge and so on for facilitate the tourist and safety reason. In case of Kaungxi Waterfall bridge they build a new one to replace the old one and this bridge is very important and really need because it connect to other side, the tourist have to use this bridge to across to other side and walk up to uper level of waterfall to see very good view from the top of waterfall.
I suggest you to go to this waterfall and see by your eye and you will find the true why they need to build this bridge.
