The Qinghai-Tibet Highway starts in Xining, the provincial seat of Qinghai, and ends in Lhasa, capital of the Tibet Autonomous Region. Open to traffic in 1954, it is the highest, longest asphalt highway in the world, with its highest point at Tanggula Pass, 5,231 meters above sea level. In winter, its surface can get as cold as minus 40 degrees centigrade.
Such a thoroughfare would not stay ooth without extensive care. Mar Dim is one of its caretakers. As head of Maintenance Squad 109, or MS109, for the 14th section in Amdo County, Mar’s mission is checking and maintaining a total length of over 40 kilometers.
Born in 1961, Mar follows the footsteps of his mother, a firstgeneration highway guardian. Since his childhood, he has learned to mend permafrost-cracked pement. Traffic has been busy because the road is the best-kept, safest highway on the roof of the world. “When I was a child, I often counted 500 trucks, each carrying tons of cement or food, passing, daily," recalls Mar.
In 1977, at the age of 16, Mar joined MS109, when the team had 40 members. They started work at 5 o’clock in the morning, with shovels on their shoulders. They usually trekked two hours to their work area. Everyone was assigned a one-kilometer section.
After some time, most of the first-generation members retired. The crew shrank to a few more than 10, so each of them had to take care of three to four kilometers – in extreme cold, with little oxygen. Even with his physical strength and local background, Mar had to recharge himself with oxygen after a long day. “Actually, I didn’t feel sick until after I turned 40,” he clarifies.
In 1985, the entire highway was reped with asphalt, and mechanization represented by all loaders made maintenance easier. They started going to work in minivans, which cut trel time to an hour.
In 2001, because of construction of the Gadla section of the Qinghai-Tibet Railway, the part of the highway under the care of MS109 saw a sudden growth in traffic for transporting building materials： As many as 10,000 vehicles passed over MS109’s charge in just 24 hours. Mar and his colleagues camped along the highway and observed the road conditions around the clock.
Tibet has opened its door wider to the outside world thanks to the improvement of its transportation from highways to railways. During the construction of the Gadla section, Mar learned to speak some Mandarin and learned more about the outside world thanks to contact with construction workers, with whom he frequently chatted over his buttered tea.
