On November 26, the Tianjin Bridge of Lancang River aided by Tianjin was built and opened to traffic, turning the deep Lancang River chasm into a thoroughfare. At an altitude of 3200 meters in Qamdo Prefecture, southwest China’s Tibet Autonomous Region, the bridge started its construction at the beginning of 2014. The total investment for the project is about 80 million yuan(about 12.5 million U.S. dollars). The bridge over the Lancang River in southwest China's Tibet Autonomous Region is  173.5 meters long. The Lancang River, known as the Mekong after it flows out of China, originates in China's Qinghai-Tibet Plateau and stretches 4,880 kilometers to the sea.
