The completely amazing natural bridge of Meghalaya:
As explained in the Daily Mail:
Deep in the rainforests of the Indian state of Meghalaya, bridges are not built, they’re grown. Ancient vines and roots of trees stretch horizontally across rivers and streams, creating a solid latticework structure strong enough to be used as a bridge…
For more than 500 years locals have guided roots and vines from the native Ficus Elastica (rubber tree) across rivers, using hollowed out trees to create root guidance systems. When they roots and vines reach the opposite bank they are allowed to take root.
In time, a sturdy living bridge is produced. Some can take ten to fifteen years to become fully functional.
