A forty-five minutes drive from village Langkawet takes one to the hamlet of Riwai, very near Mawlynnong, where the finest living root specimen is found. Impressive by its huge size, it is probably the largest, and the oldest, living root bridge in the region. Spanning the Wahthyllong River, it is about 40 feet in length and 7 feet wide. Created about 150 years ago, the bridge was art in organic engineering. It was built by planting two bamboo trees on each bank of the rapid. A bamboo was initially planked across it to secure the roots from both the trees. With time, the roots superseded the original bamboo plank and then over the centuries weaved themselves around it in intricate networks across.
