The structural integrity of the bridge is sustained by the continuous growth of rubber tree roots, which can live for several centuries.
The process of 'training' the roots involves guiding them through hollowed-out betel nut tree trunks to provide direction across the water.
It takes between 15 to 30 years for a living root bridge to become fully functional for human use.
The bridge is located in Mawlynnong, a village often cited for its high standards of community-led cleanliness and hygiene.
The high humidity and heavy rainfall in Meghalaya provide the ideal biological conditions for the Ficus elastica to flourish.
The Riwai Living Root Bridge is a bio-engineered crossing formed by training the aerial roots of Ficus elastica trees over several decades. Located near the village of Riwai in Meghalaya, this structural marvel connects the forest canopy to the ground across a mountain stream. The Khasi and Jaintia tribes traditionally cultivate these bridges to traverse deep valleys and rivers during the monsoon season when water levels rise significantly. Unlike man-made bridges, these structures strengthen over time as the living roots continue to grow and thicken. The bridge spans approximately 50 feet and features a deck reinforced with stones and wooden planks to support foot traffic. It serves as a primary functional link for local villagers despite its status as a significant regional landmark.
From the trail level looking up at the bridge structure, or from the bank directly opposite the span.
Wear footwear with strong grip as the roots can become slippery when damp.
Cross one at a time to minimize vibration and protect the integrity of the root system.
Carry a light rain jacket regardless of the season due to unpredictable mountain weather.
Do not attempt to walk on the bridge during heavy rainfall if the local authorities have flagged the path as dangerous.
Avoid jumping or running on the bridge; do not touch or pull at the young root tendrils.
