During monsoon season in northeast India, rainwater gushes through the emerald valleys and deep gorges of Meghalaya, the“abode of the clouds.” The mountainous plateau between Assam and Bangladesh is one of the wettest places on Earth, and the Khasi tribes who inhabit these hills have developed an intimate relationship with the forest.
Long before the availability of modern construction materials, the Khasi devised an ingenious way to traverse the turbulent waterways and link isolated villages: living root bridges, locally known as jing kieng jri.
Tree trunks are planted on each side of the bank to create a sturdy foundation, and over the course of 15 to 30 years, the Khasi slowly thread Ficus elastica roots across a temporary bamboo scaffolding to connect the gap. A combination of humidity and foot traffic help compact the soil over time, and the tangle of roots grows thick and strong. Mature bridges stretch 15 to 250 feet over deep rivers and gorges, and can bear impressive loads—upwards of 35 people at a time.
Unlike modern building materials like concrete and steel, these structures typically become more resilient with age and can survive centuries. They regularly withstand flash flooding and storm surges that are common in the region—a low-cost and sustainable way to connect remote mountain villages scattered throughout the steep terrain. The exact origin of the tradition in this region is unknown, but the first written record appears more than a hundred years ago.
