After seeing the distinctive landscape on both sides of the Nu River, I continued to ride along the Nu River. I could see the mysterious Nu River Bridge on National Highway 318 soon after passing through the tunnel. The Nu River Bridge is located between Bangda Town and Basu County. After walking on Nu River 72, I could see it not far away. Across the fast-flowing Nu River, there are steep cliffs on both sides, and it is difficult to imagine the difficulty of building a bridge between such cliffs in the 1950s.
