| Beipanjiang Bridge What is the world’s highest bridge? It’s China’s Beipanjiang Bridge. Standing over the Beipan River, it is 565 meters tall. It’s 1,341.4 meters long and 720 meters wide. It connects Yunnan province with Guizhou province. | Shandan Junmachang Station Shandan Junmachang Station is the world’s highest high-speed railway station. It was built in Gansu province. It stands at a sea level of 3, 108 meters. The average temperature is around -4°C. |
| Daocheng Yading Airport It lies in Sichuan province. It is the world’s highest airport. There are 1,145 small lakes around it, which are the result of the movement of ancient glaciers (冰川). | Zhegu Wind Farm It stands in the hills of the Himalayas in Tibet. That made it the world’s highest wind farm. The farm has set an example for high-altitude (海拔) wind power scientific research. |
