Root Bridges (India)
It’s hard to tell this bridge apart from the rest of the woodland. To put it simply, it was never constructed in the first place.

The bridge was essentially a product of the forest’s natural materials. There is a natural bridge made up of the Ficus elastica tree roots. Tribes like War-Khasis knew how to make trees grow their roots in the appropriate way so that they could build these lovely bridges across the water.
