The Lhasa-Nyingchi highway has been in operation for two years.
The 409.2-kilometer highway links Lhasa, capital of southwest China's Tibet Autonomous Region, and Nyingchi.
It slashes travel time between the two cities in Tibet from 8 hours to 4 hours.
Over the past two years, it also helps improve local people's lives thanks to the booming tourism industry that has been benefited from the opening of the highway.
