On December 26, an important moment in the history of Hunan transportation construction ushered in an important moment, the first "four to eight" expressway reconstruction and expansion project - G4 Beijing-Hong Kong-Macao Expressway Leiyang City to Yizhang (Hunan and Guangdong boundary) section of the reconstruction and expansion project (hereinafter referred to as the "Leiyi reconstruction and expansion project") The transportation organization plan was officially released.
This indicates that Hunan is about to enter a new stage of highway expansion construction, and also opens the prelude to the implementation of the "14th Five-Year Plan" transportation development plan of Hunan Province.
The project is expected in:It will be fully launched in the first half of 2024, with a total construction period of 3 years. During construction, the speed limit will be adjusted to 60 km/hto ensure the quality of the project and the safety of the construction. At present, the project has started the construction of Leishui Bridge and Yizhang North Interchange, and the third branch of the general contracting project department of the project consortium has successfully completed the prefabricated test production of the guardrail in the middle division, which provides a strong guarantee for the subsequent formal start of construction.
The Leiyi reconstruction and expansion project is not only an important part of the national highway network G4 Beijing-Hong Kong-Macao Expressway, but also a key construction project in the "14th Five-Year Plan" transportation development plan of Hunan Province.
The completion and opening of the project will greatly smooth the transportation of Hunan Province to the north and south of the Yangtze River urban agglomeration and the Guangdong-Hong Kong-Macao Greater Bay Area in the south, which is of great significance for improving the comprehensive transportation system of Hunan Province, enhancing the ability of southern Hunan to undertake industrial gradient transfer, and promoting the industrial upgrading of Hunan Province.
The total length of the route of the project is 144309 kilometers, using the two-way eight-lane highway standard to reconstruct and expand the old road. Wherein, the starting point of the city hub to the Wuli pai interchange section design speed of 120 kilometers h, roadbed width of 415 m;The design speed of the Wuli pai interchange to the end section is 100 kilometers per hour, and the width of the roadbed is 41 meters. At the same time, the project will also add facilities such as Chenzhou service area and Leiyang interchange.
Leiyang South Interchange (new).
Chenzhou service area (new).
Leishui Bridge (detached, newly built and widened).
Ma Tian Interchange (in-situ reconstruction).

According to the traffic organization plan, the Leiyi reconstruction and expansion project will adopt the "road network to induce diversion, the overall two-way four-lane guarantee, partial.
2. Three-lane Baotong" traffic organization design plan, and set up standing diversion points, timely start the "high connection" emergency diversion. This option will minimize the impact on traffic during construction and ensure smooth traffic.
In order to ensure that during the construction period, the traffic of G4 Beijing-Hong Kong-Macao Expressway and G76 Xiarong Expressway and Hunan Expressway S31 Yifeng Expressway will not be affected, Hunan Expressway Group has formulated a thorough traffic organization plan.
At the heart of this approach is the idea that even if construction is carried out in the interchange area, it will ensure a smooth flow of traffic throughout the entire process and avoid any form of traffic disruption.
The construction environment of the Leiyi Reconstruction and Expansion Project is quite complex, involving not only multiple environmentally sensitive areas, but also coordination with multiple intersections and railway lines. In the face of these challenges, Hunan Expressway Group will give full play to its advantages in the coordination and linkage mechanism to guide and supervise the construction and development of the Weiyi Zero Road Expressway in Hunan Province to ensure that all work responsibilities are effectively implemented.
Through this series of well-planned measures, Hunan Expressway Group aims not only to ensure the smooth implementation of the Leiyi reconstruction and expansion project, but also to enhance the travel experience of the public during the construction period.
This means that even during the construction period, the public should feel the convenience, comfort and safety of travel, so as to improve the public's sense of gain, happiness and security.
This series of efforts not only reflects Hunan Expressway Group's deep understanding of social responsibility, but also demonstrates its efficient management ability in transportation infrastructure construction.
With the steady progress of the Leiyi reconstruction and expansion project, Hunan's expressway network will be more perfect, injecting new vitality into the economic development and social progress of Hunan and the entire region.
We look forward to the smooth progress of this project and the bright future of Hunan Transportation.
