According to the news of Xinhua News Agency Sept. 9, Chinese railway workers have completed a 131-km work road for the construction of the highest section of the Qinghai-Tibet Railway, the highest of its kind in the world.

Winding through a mountain 5,072 meters above sea level, the work road was built to transport materials for the construction of the world's toughest railway project. Its completion paved the way for the construction of the highest section of the railway, according to officials overseeing the construction of the project.

The road was built through an uninhabited area in the Tanggula mountains on the Qinghai-Tibet Plateau. The oxygen content in the air there is only half that in coastal areas and the earth is permanently frozen, making the construction extremely difficult.

When completed, the 1,956-km Qinghai-Tibet Railway will link Xining, capital of Qinghai Province in northwest China, with Lhasa, capital of Tibet in southwest China.
