Why did the Sichuan-Tibet driver throw cigarette butts?Uncover the clever move
The Sichuan-Tibet Line is one of the highest and longest highways in China and one of the most beautiful highways in the world.
It connects Sichuan Province and ** Autonomous Region in southwestern China and is 2,179 kilometers long and traverses 14 high mountains above 4,000 meters above sea level.
Traversing multiple rivers and passing countless bridges, tunnels and bends, the scenery along the way is breathtaking, and the scenery is always changing.
It's not just a road, it's a hero's road.
Features of the Sichuan-Tibet line.
The Sichuan-Tibet line is about 2,140 kilometers long and is divided into a southern and northern route.
The southern route is National Highway 318, which runs from Chengdu to Lhasa, passing through Ya'an, Kangding, Xinduqiao, Daocheng Yading, Mangkang, Bomi and Nyingchi.
The northern route is National Highway 317, which runs from Chengdu to Qamdo, passing through Wolong, Malkang, Seda, Dege, Jiangda, Ba Qing, and Nagqu.
The two routes converge at Chamdo and then follow National Highway 109 to Lhasa.
The construction and development of the Sichuan-Tibet line is an arduous project and a major undertaking, and its characteristics can be summed up in four words: high, cold, dangerous, and beautiful.
With an average elevation of more than 4,000 meters above sea level, and the highest point, Tanggula Pass, at 5,231 meters above sea level, it is the highest highway in the world.
The altitude here is low, with the lowest point being only 500 meters and the highest point exceeding 5000 meters.
There are 12 mountain passes with an altitude of more than 5000 meters along the way, which have brought many difficulties and challenges to people's lives and work.
The climatic conditions here are very harsh, with low temperatures all year round, long winters and short summers, more snow and longer ice covers.
The minimum temperature can reach minus 40 degrees Celsius and the maximum temperature does not exceed 20 degrees Celsius.
In addition, the geological conditions are very complex, natural disasters such as landslides and mudslides occur from time to time, the traffic is inconvenient, the road conditions are difficult and dangerous, and some places can only be crossed by car.
In some places, there are no roads at all, and they can only rely on human or animal power to advance, which brings great difficulties and damage to road construction and maintenance.
Even the roads are in very bad condition, mostly gravel and dirt roads, the road surface is narrow, and the roadbed is soft, which brings many threats and tests to people's safety and life.
But the scenery along the way is beautiful, the natural scenery is magnificent, and a rich ecosystem and biodiversity are formed.
The sad story of the construction of the Sichuan-Tibet Highway.
The construction of the Sichuan-Tibet line is a story full of hardships and sacrifices, but also a story full of struggle and glory.
The predecessor of the Sichuan-Tibet Line was the Ancient Tea Horse Road, which is an important channel for economic and cultural exchanges between Sichuan and Tibet.
However, due to geographical and political reasons, this old road has never been turned into a full-fledged highway.
The construction of the Sichuan-Tibet line began in 1950 and went through three stages. In 1950, the Chinese People's Liberation Army entered ** and began the initial construction of the Sichuan-Tibet line to ensure the transportation of military supplies.
In 1954, the Sichuan-Tibet Line was officially opened to traffic, with a total length of 2,413 kilometers, of which more than 1,800 kilometers were dirt roads, and an average of 1 per kilometer needed to be built5 bridges, each kilometer of which required the blasting of 15,000 cubic meters of mountain.
The initial construction of the Sichuan-Tibet line lasted four years, mobilized more than 200,000 people, sacrificed more than 3,000 people, and created a miracle in the history of road construction in the world.
In 1960, in order to adapt to the economic development and social stability, the reconstruction project of the Sichuan-Tibet line was implemented.
In 1974, the reconstruction project of the Sichuan-Tibet line was completed, with a total length of 2,179 kilometers, of which more than 1,400 kilometers were gravel roads, with an average of two bridges per kilometer and 20,000 cubic meters of mountains to be blasted per kilometer.
The reconstruction of the Sichuan-Tibet Highway took 14 years, mobilized more than 400,000 people, and sacrificed more than 5,000 people, setting a new record in the history of road construction in the world.
In 1984, the Sichuan-Tibet line began to be expanded to meet the needs of tourism and people's livelihood.
In 2004, the Sichuan-Tibet Line expansion project was completed, with a total length of 2,179 kilometers, of which more than 1,600 kilometers were paved roads, with an average of 3 bridges per kilometer and 30,000 cubic meters per kilometer.
The Sichuan-Tibet Line expansion project, which lasted 20 years, mobilized more than 600,000 people and sacrificed more than 7,000 people, once again created a myth in the history of road construction in the world.
In addition to their direct involvement in the road construction project, the Tibetan compatriots also organized a huge transport fleet, with the first batch of 6,000 yaks coming from Shiqu County, Ganzi Tibetan Autonomous Prefecture, at the source of the Yalong River.
In order to open up the Sichuan-Tibet line, more than 1 million yaks were mobilized in the ** region, and 600,000 bags of materials were transported with animal power.
The northern and southern lines were built almost simultaneously, with the northern line officially opened in December 1954 and the southern line fully completed and opened in 1969.
In the process of building the Sichuan-Tibet and Qinghai-Tibet highways, more than 3,000 cadres, soldiers and workers died bravely, and the achievements of that generation will go down in history.
Salute to the martyrs.
The builders of the Sichuan-Tibet line are a group of unsung heroes who have built an eternal monument for the reunification and development of the motherland and for the peace and progress of the motherland with their blood, sweat and lives.
Their spirit deserves to be remembered and Xi forever, which is why many drivers light a cigarette while driving and throw the cigarette butt out the window.
