Root Bridges: Bio-Engineering of the Khasi Hills

### Technical Briefing: Living Root Bridges The Living Root Bridges of Meghalaya are wonders of sustainable bio-engineering, crafted by the Khasi and Jaintia tribes over generations. #### 1. Structural Integrity These bridges are made from the aerial roots of Ficus elastica trees. They are trained over decades to span rivers and gorges. - **Lifespan**: Unlike timber or steel, these bridges grow stronger with age, lasting up to 500 years. - **The Double Decker**: Located in Nongriat, this is the most famous example of multi-layered root bridge construction. #### 2. The Nongriat Trace Accessing the double-decker bridge requires a descent of over 3,000 stone steps. - **Physical Load**: High. - **Safety**: Ensure proper trekking gear and hydration. #### 3. Weather Sensitivity The bridges are most impressive during the monsoon, but the trails can be slippery. The post-monsoon window (Oct-Nov) offers the best visibility for photography.
