Longbai expressway-officially started.
On June 23rd, 2007, the national key project from Longlin, Guangxi Zhuang Autonomous Region to expressway, Baise started in Baise.
Longbai expressway is an important part of Shankun expressway in "79 18" national highway network planning, and also an important part of Hezhou-Longlin highway in "4 vertical and 6 horizontal" expressway network planning. It is one of the most convenient highway passages in Guangxi and Yunnan-Guizhou provinces, and also an important sea passage in southwest China. The project starts from Pingban Town, Longlin County, at the junction of Guizhou and Guangxi provinces, connects Xingyi, Guizhou Province to Bamba expressway, passes through Longlin, Tianlin and Youjiang District of Baise City, ends in Sitang Town, Youjiang District of Baise City, and connects Nanning to Baise expressway. The whole line is constructed according to the four-lane expressway standard, with the main line length of176.7km.. The estimated investment of the project is RMB 65,438+0,065,438+0.25 billion, of which US$ 300 million is borrowed from the Asian Development Bank, making it the most foreign-funded project in expressway over the years.
Longbai expressway-officially opened to traffic
Longbai expressway was completed on 201kloc-0/65438+127 October. It is the first expressway in China to adopt rubber asphalt pavement construction technology on a large scale, with a total of 200,000 discarded tires.
Longbai expressway is a section of Shankun expressway, Guangxi, which is planned by the National expressway Network. It is the most convenient highway connecting Yunnan and Guizhou provinces, with a total length of 177.5 16 km. Construction officially started on August 8, 2008, with a total investment of 10784 million yuan.
It is understood that this section of expressway has the "three best" in the history of highway construction in Guangxi: First, the proportion of bridges and tunnels in the total length of the route reaches 32%, which is the highest among the completed expressway. Bridges are interconnected and meander between mountains. For example, there are 7 tunnels in Tianlin, almost end to end, crossing the entire hillside in the northeast of the city, and the longest tunnel is close to 2 kilometers; Second, the investment scale is the largest, and it is the first expressway under construction in Guangxi with an investment of over 10 billion yuan, with a cost of 60 million yuan per kilometer; Third, the construction conditions are the hardest. The project is located in the mountainous area of southwest Guangxi and belongs to the transitional zone on the edge of Yunnan-Guizhou Plateau. The terrain is mainly mountainous and the geological conditions are very complicated. The route is mainly arranged along the narrow valley corridor.
In addition, the biggest feature of Longbai Expressway is that the pavement is paved with rubber asphalt, which is the first expressway in Guangxi to use rubber asphalt, and * * * consumes 200,000 waste tires. When vehicles are driving on the road, they obviously feel that the noise is reduced and stable, and it is an eco-friendly and low-carbon expressway.
Longbai expressway-Meaning
The construction of this project is of great significance to further improve the national and Guangxi expressway network, improve regional traffic conditions, strengthen economic and social ties between Guangxi and Guizhou, and promote sound and rapid economic and social development in Guangxi. At the same time, it is also of great significance to promote the western development and pan-Pearl River Delta economic cooperation, and accelerate the opening and development of Guangxi Beibu Gulf Economic Zone and the construction of China-ASEAN Free Trade Area. More than 70% of Guangxi's coal must be imported from Guizhou, and there was no shortcut between the two provinces before. Longbai Expressway will shoulder this responsibility and play a role in helping local people get rid of poverty. In addition, together with the Nanning-Kunming Railway, it will form the most convenient sea and exit passage in southwest China, and it will also be an international passage connecting China and ASEAN countries.
The terminal section of the route is14.4km, which is a part of Baise Ring Expressway, and the rest sections are part of National expressway Network-Shankun Expressway.
