YayeHighwaysIt is a connection to Sichuan ProvinceYa'anAn important passage between the city and Yecheng County, Kashgar Prefecture, Xinjiang Uygur Autonomous Region. At present, the Yaye Expressway is divided into several construction stages, of which the sections that have been opened to traffic include:Lhasato the Shigatse sectionNyingchiToLhasaparagraphsYa'anto Kangding section, etc. There are also some sections that are still being planned, such as the Kangding-Xindu bridge section. With a total length of about 3,900 kilometers and a design speed of 80-100 kilometers per hour, Yaye Expressway is a western region of great strategic significance and economic valueHighways
YayeHighwaysThe construction of the construction is essential for promoting the economic development of the western region andTransportationConvenience is important. It is important not only from Sichuan to XinjiangTransportationBonds, but also the most important in the regionHighwaysOne. The completion of the Yaye Expressway will strengthen the connection between the western region and other regions, promote the coordinated development of the region, and help strengthen the unity and exchanges between various ethnic groups.
YayeHighwaysCrossing the entire Qinghai-Tibet Plateau, one of its characteristics is that bridges and tunnels account for more than 80%. WholeHighwaysThe average altitude is more than 3,000 meters, with the highest altitude reaching 4,500 meters. This also means that Yaye Expressway is facing complex geological and climatic conditions, which brings great challenges to the construction.
In order to cope with the geological conditions of the plateau, the design of the Yaye Expressway adopts advanced tunnel and bridge technology. It is expected that the number of tunnels will reach 50 and the number of bridges will exceed 100. Among them, the ultra-long tunnel group of Sejila Mountain Tunnel, Tongmai Tunnel and Yigong Tunnel is more than 100 kilometers long. The construction of these tunnels and bridges will greatly improve the transportation efficiency and safety of the Yaye Expressway.
At present, there are still some sections of Yaye Expressway in the planning stage and the construction has not yet started. First of all,LhasaConstruction has begun on the section to Shigatse and is expected to be opened to traffic by the end of 2024. Secondly, the Kangding-Xindu bridge section is scheduled to start in 2022, with an estimated construction period of 4 years. The timing of the construction of the other planned sections has not yet been determined.
However, the difficulty and cost of the construction of the Yaye Expressway cannot be ignored. The high altitude, complex geological conditions, and the security situation at the border all posed challenges to the project. Therefore, it is not certain about the full penetration time of Yaye Expressway. According to the opinions of experts and netizens, it is unlikely that the whole process will be opened to traffic in the short term.
However, there is optimism about China's infrastructure capacity and national will. While there are some challenges to the current construction challenges and the asymmetry of return on investment, it is generally believed that over time, the Yaye Expressway will eventually be fully connected. It is believed that the design scheme of the tunnel and bridge has been determined, and Litang toNyingchiConstruction of the section is expected to begin in 2025 and will take about 10 years. When the section of the road is completed and opened to traffic, it will be shortened to ChengduLhasaThe travel time brings more convenience to ** travel and so on.
To sum up, YayeHighwaysThe construction is of great significance and broad prospects. Although there are still some challenges, we have reason to believe in China's infrastructure capacity and national determination. The completion of the Yaye Expressway will further promote the development of the western region, strengthen inter-regional contacts and exchanges, and contribute to the development of China's eastern and western regionsNational unityPitch in.
