Situated at Laitkynsew village, the Umnnoi living root bridge is a 53 ft long bridge. Locally known as 'Jingkieng Deingjri' which means 'bridge of the rubber tree,' this bridge is remarkable in that it is more than a 100 years old.
Root bridges are made by an ingenious technique. The tiny, hair-thin, hanging roots of a particular Banyan tree are intertwined with boughs and twigs and allowed to grow naturally. After a few years the intertwined roots and branches would become strong enough for people to use it as the bridge across the stream. The chief advantage of a root bridge is that it does not get washed away by the strong currents of the rains, but remains permanent and in fact grows stronger year by year.
