Incredible India! Root Bridges, Cherrapunji

Renowned as one of the most rain receiving places in India and world, Cherrapunji is equally famous for Root Bridges. Fondly it called that Cherrapunji is a place where bridges are not built, they’re grown.

In the wettest place on this earth, the living bridges of Cherrapunji, India are made from the roots of the Ficus elastica tree. This tree produces a series of secondary roots from higher up its trunk and can comfortably perch atop huge boulders along the riverbanks, or even in the middle of the rivers themselves. In order to make a rubber tree's roots grow in the right direction - say, over a river - the Khasis (local tribe) use betel nut trunks, sliced down the middle and hollowed out, to create root-guidance systems.

The thin, tender roots of the rubber tree, prevented from fanning out by the betel nut trunks, grow straight out. When they reach the other side of the river, they're allowed to take root in the soil. Given enough time, a sturdy, living bridge is produced. The root bridges, some of which are over a hundred feet long, take ten to fifteen years to become fully functional, but they're extraordinarily strong - strong enough that some of them can support the weight of fifty or more people at a time.

Unlike bridges built by man, which weaken over a period of time, these don’t. Because they are alive and still growing, the bridges actually gain strength over time - and some of the ancient root bridges used daily by the people of the villages around Cherrapunji may be well over five hundred years old. One special root bridge, believed to be the only one of its kind in the world, is actually two bridges stacked one over the other and has come to be known as the "Umshiang Double-Decker Root Bridge."
