Tomorrow to open to traffic, these two expressways (sections) are open to traffic synchronously On December 18, the reporter learned from the Hunan Provincial Expressway Group that on the morning of December 19, the Guanxin Expressway was officially opened to traffic, and the S20 Pingdong Expressway Shuangqiao Hub to Anhua Toll Station section was opened to traffic simultaneously.
After the opening of the Guanxin Expressway, it means that the Hunan section of the Hubei Expressway will add another stroke, completely end the history of the Yiyang Anhua Zhexi reservoir area without expressways, connect the traffic arteries in the central and northern parts of Hunan Province, and become an important passage from the central and western regions of Hunan Province to Hubei, Guangxi, Jiangxi and even East China.
Guanxin Expressway is an important part of the G59 Hubei Expressway, starting from Muhaopu, Guanzhuang Town, Yuanling County, Huaihua City, Hunan Province, Xi'an Town, Taoyuan County, Changde City, Malu Town, Zhexi Town, Nanjin Township, Gulou Township, Pingkou Town, Anhua County, Yiyang City, and ending at Shuikoukeng, Langtang Town, Xinhua County, Loudi City, connecting to S50 Changzhi Expressway. The total length of the main line is 76581 kilometers, according to the standard construction of four-lane expressway, the whole line set up 2 service areas of Caomuyuan and Gulou service area, Taoyuan Xi'an, Anhua West, Xin'an, Nanjin toll station 4 toll stations.
It is worth mentioning that the proportion of bridges and tunnels in the new high-speed is as high as 74%, including 106 bridges and 22 tunnels. Among them, the special bridges include the largest span (span diameter of 500 meters) steel-concrete girder composite cable-stayed bridge under construction in Hunan Province - Xuefeng Lake Bridge;The extra-long tunnel has a length of 4333The 5-metre Kowloon Pool Tunnel and the 3,502-metre-long Chun Shue Shan Tunnel. Because the route passes through the mountainous area of central Hunan, the terrain and geological conditions are complex, passing through many cliffs and deep ravines, the maximum relative height difference of the same section is more than 200 meters, the geology along the line is mainly argillaceous slate and sandy slate, the degree of weathering is high, the stability is poor, it is the highway construction project with the highest proportion of bridges and tunnels in Hunan Province at present, and the construction difficulty is the largest.
As an important part of the "seven vertical and eight horizontal" expressway network in Hunan Province, the Guanxin Expressway will connect the expressways that have been built and are under construction in Hunan Province into a network after opening to traffic, connecting Anhua and Huaihua, Changde, Yiyang, Loudi and other places, making it more convenient to "travel from south to north and go west".
The Zhexi reservoir area of Anhua County is rich in natural resources, but due to the limitation of topography and landform, in the past, the daily travel and material transportation of the people in the reservoir areas such as Nanjin and Gulou mainly relied on waterways and a low-grade winding mountain road with a length of 60 kilometers and more than 600 bends. Xia Zanwen, former director of the Joint Working Committee of the CPPCC in Nanjin Township, said: "It takes more than three hours for the people in the reservoir areas such as Nanjin and Gulou to get to the county seat by boat at the earliest, and it is difficult for the 300,000 people in the reservoir area to travel, which has become a bottleneck restricting the economic and social development of the reservoir area. ”
After the opening of the Guanxin Expressway, the time for villagers in the townships and towns of the Anhua reservoir area to drive to the county seat will be shortened from three or four hours to 30 or 40 minutes, and the time to Changsha in Hunan Province will be shortened from one day to two and a half hours. The relevant person in charge of the construction and development of the Guanxin Expressway in Hunan Province said.
