Describe the significance of living root bridges in Meghalaya and how they are constructed.

Living root bridges, called jingkieng jri in Khasi language, are crafted by the Khāsi and Jaintia tribes of Meghalaya using roots of Ficus elastica trees. Indigenous people guide roots across streams with bamboo and palm trunks. Over decades or centuries, roots grow stronger and twist into natural bridges standing 15–30 metres high. These living structures reflect local knowledge about nature, have cultural meaning, and connect generations.
