Why is it so slow to get from Golmud to Lhasa?

High altitude and complex terrain, road conditions and safety considerations.

1, with high altitude and complex terrain. The route from Golmud to Lhasa passes through the Qinghai-Tibet Plateau with high altitude and complex terrain, which means that road construction and maintenance are relatively difficult, and it also increases the difficulty and speed limit of vehicle driving.

2. Road conditions. Although the traffic routes on the Qinghai-Tibet Plateau have been improved, there are still some areas with poor road conditions, such as mountains, deserts and plateaus. There are bends, ramps and gravel roads in these sections, which limit the speed of vehicles.

3. Safety considerations. The climatic conditions in the Qinghai-Tibet Plateau are changeable and the weather is unstable, and there will be bad weather conditions, such as ice and snow and strong winds. In order to ensure safety, vehicles need to slow down.
