Recently, a reporter from Jiandao.com learned that according to the notice issued by the Ministry of Transport and the National Development and Reform Commission on the "Implementation Plan for Quality Improvement and Reconstruction of the Sichuan-Tibet Highway G318 Line", the Sichuan-Tibet Highway G318 Line Quality Improvement and Reconstruction Project in Tibet is divided into 11 sections. At present, the Mangkang border crossing project, the Basu border crossing project, and the section from Tiantuo village to Genyao village in Qamdo have started construction.

Upgrading and renovation project

Speaking of National Highway 318, it can be said to be a landscape avenue for many people who drive in and out of Tibet. Line G318 of the Sichuan-Tibet Highway starts from Chengdu, passes through cities and counties such as Ya'an, Kangding, Mangkang, Bomi, Linzhi, and ends in Lhasa, with a total length of about 2,083 kilometers. The G318 line of the Sichuan-Tibet Highway was first built in the 1950s. After years of renovation and reconstruction, the disaster resistance capacity, traffic capacity and service level of the highway have been greatly improved. However, due to the extremely complex terrain and geological conditions, the extremely special natural climate and the extremely fragile ecological environment, some road sections have low technical grades and weak disaster resistance capabilities. Traffic congestion and peak tourist season are more prominent, making it difficult to meet the needs of regional economic and social development. During the construction of the Sichuan-Tibet Railway, the pressure on road traffic will be further aggravated.

According to the requirements of the "Implementation Plan for Quality Improvement and Reconstruction of Sichuan-Tibet Highway G318 Line" issued by the Ministry of Transport and the National Development and Reform Commission, the Transportation Department of the Tibet Autonomous Region has officially launched the implementation of the quality improvement project of the Sichuan-Tibet Highway G318 Line, which will help further strengthen Tibet. The close connection with other provinces and cities can promote the flow of production and living materials, drive economic and social development along the line and improve people's livelihood; it is conducive to further improving the traffic capacity and service level of the highway, and ensuring the transportation needs of Sichuan-Tibet railway construction materials.

3 projects in Qamdo have started

Recently, it was learned from the project headquarters of the Sichuan-Tibet Highway G318 Line Quality Improvement and Reconstruction Project (Chamdo Territory) that the Sichuan-Tibet Highway G318 Line Quality Improvement and Transformation Project in Tibet is divided into 11 sections. At present, the three projects of Mangkang Transit Line Project, Basu Transit Line Project, and Tiantuo Village-Genyao Village Section Project located in Qamdo have started construction on December 15, 2022, and the three projects are all in Qamdo City.

The Mangkang crossing line project has a total length of 1.7 kilometers, a design speed of 40 kilometers per hour, and an asphalt concrete road surface. The Basu border crossing line project has a total length of 9.2 kilometers and a design speed of 40 kilometers per hour. In the future, it will be built into a sightseeing spot with bridges, sidewalks and landscape lights. The section from Tiantuo Village to Genyao Village has a total length of 93 kilometers, of which 50 kilometers are for upgrading and upgrading, and the design speed is 30 (20) kilometers per hour. At present, a series of work, such as cage making and pouring, is being carried out in an orderly manner for the section from Tiantuo Village to Genyao Village.

The Sichuan-Tibet Highway G318 Line Quality Improvement and Reconstruction Project Disaster Affected Point Remediation Project in Tibet is located in Qamdo and Nyingchi, with a total route length of 364.025 kilometers. Disaster-affected point regulation project maintains the original road technical standards, does not adjust the existing horizontal and vertical indicators, and mainly treats the geological disasters distributed along the line separately, solves the problem of road disconnection caused by the outbreak of geological disasters in the road section, and improves road transportation. safety and traffic efficiency.

It is reported that during the implementation of the quality improvement and renovation project of the G318 line of the Sichuan-Tibet Highway, measures such as half traffic and half construction, as well as interval traffic control, will be implemented to ensure that both traffic and construction are correct during the construction period. After the completion of the project, it will further improve the highway traffic capacity and service level, and guarantee and support the construction of the Sichuan-Tibet Railway, which is of great significance to promoting regional economic and social development.
