This is known worldwide as one of the most unique naturally formed structures that stands strongly since its inception. It is frequented by travellers from around the world. The trek to the bridge located in Nongriat village, Cherapunjee is not for the faint hearted. Meghalaya’s double-decker and single-decker root bridges are unique in the world and are a remarkable sight. The bridges are tangles of massive thick roots, which have been intermingled to form a bridge that can hold several people at a time. Khasi people have been trained to grow these bridges across the raised banks of streams to form a solid bridge, made from roots. The living bridges are made from the roots of the Ficuselastica tree, which produces a series of secondary roots that are perched atop huge boulders along the streams or the riverbanks. The root bridges, some of which are over a hundred feet long, take ten to fifteen years to become fully functional, but they are extraordinarily strong – strong enough that some of them can support the weight of fifty or more people at a time. The bridges are alive and still growing and gain strength over time.
