The Living Root Bridges is made out of all natural support like from the roots of a rubber fig tree or tying the roots with bamboo shoots and more. Tying the root at an early stage ensures that after a particular time the roots will grow tighter and stronger and will help in creating a bridge. This culture was initiated by the Khasi and the Jaintia people from the Shillong Plateau (eastern India), but there is no record of when this culture was initiated. Ficus Elastica Tree is known for its strength hence this plant species is commonly used for creating a root bridge; it helps in anchoring the roots and tree even with rocky surface and with slopes.
Since the condition of the roots are checked regularly during the early days so that the life span of the root bridge lasts up to 100 years and a healthy root bridge does last more than 100 years. As long as the tree is healthy, the roots will be able to regrow and strengthen the bonds of the bridge.
