The development and upkeep of bridges is a community affair. Initially, a length of bamboo is secured across a river divide and a banyan plant,
Ficus benghalensis is planted on each bank. Over the months and years, the roots and branches of the rapidly growing Ficus are trained along the bamboo until they meet in the middle and eventually supersede its support. At later stages in the evolution of the bridge, stones are inserted into the gaps and eventually become engulfed by the plant forming the beautiful walkways. Later still, the bridges are improved upon with the addition of hand rails and steps.
