Introduction to the Qinghai-Tibet Sichuan-Tibet Highway Monument: On the bank of the Lhasa River, there is also a Qinghai-Tibet Sichuan-Tibet Highway Monument. This was built on December 25, 1984 to commemorate the 30th anniversary of the opening of the Qinghai-Tibet Sichuan-Tibet Highway. Another twenty years have passed, and the Qinghai-Tibet Railway has been opened to traffic, but the Qinghai-Tibet Highway and the Sichuan-Tibet Highway are still the transportation arteries of Tibet.
