On January 3, the Chongqing Chengkou to Kaizhou Expressway (hereinafter referred to as "Chengkai Expressway") Chengkou County to Beiping section was completed and opened to traffic, and will be officially opened to public vehicles at 15 o'clock today. This section of the highway will become the first section of the expressway to be completed and opened to traffic in Chongqing in 2024, and Chongqing's transportation construction has ushered in a "good start" of the year.
Chengkai Expressway is an important section of the national high-speed G69 Yinbai Expressway, and belongs to the tenth shot of Chongqing's "Four Rings, 22 Shots and 60 Links" expressway planning. The project starts from the Shaanxi-Chongqing boundary of Daba Mountain, passes through Beiping, County Town, Tatezi, Jiming, Xuebaoshan in Chengkou County, Manyue, Dajin, Hot Springs, Baihe in Kaizhou District, and ends at Zhaojia Interchange of Wankai Expressway, with a total length of 128.5 kilometers and a total investment of 23.45 billion yuan, which is constructed according to the standard of two-way four-lane expressway, with a design speed of 80 km/h and a construction period of 6 years. The project adopts the construction mode of starting construction in sections and opening to traffic in sections, of which about 110 kilometers from Zhaojia to Chengkou County in Kaizhou has been completed and opened to traffic, and the section is about 11 kilometers from Chengkou County to Beiping, taking Class 1 passenger cars as an example, and the high-speed fee for this section is 7 yuan.
The section from Chengkou County to Beiping of Chengkai Expressway is the northernmost section of the expressway network in Chongqing, with complex geological conditions along the route and extremely high requirements for construction management, safety control and environmental protection. In particular, the Luojialiang Tunnel, a controlled project, has a maximum buried depth of 1,010 meters and crosses about 400 meters of the "City Bus Fault Zone". During the construction process, China Railway 12th Bureau and other participating units carefully organized and scientifically implemented policies to successfully complete the tunnel construction task and achieve the target task of opening this section to traffic ahead of schedule.
Hu Xuhui, general manager of the construction management department of Chongqing Expressway Group, secretary of the party committee and executive director of the consulting company, introduced that the remaining 7 kilometers of the remaining section from Beiping to Shaanxi-Chongqing Province of the Chengkai Expressway are also under construction, of which the 13.6-kilometer-long Dabashan Tunnel (including 5.4 kilometers of the Chongqing section) has been excavated to 73% of the total mileage, and strive to be completed and opened to traffic at the same time as the Shaanxi section by the end of 2025.
According to the Chongqing Municipal Transportation Bureau, after the opening of the Chengkou County to Beiping section of the Chengkou Expressway, the passage time from Chengkou Beiping Township to the county seat will be more than doubled, and the whole high-speed direct access to Kaizhou and Wanzhou regions will be realized, which will greatly facilitate the travel of local people. At the same time, it will also promote the "going out" of local specialties such as lacquer and walnuts in Beiping Township, Chengkou County, drive the rapid development of tourism resources around Beiping Township, attract tourists from outside the region to "come in", and provide new impetus for the rural revitalization and development of Qinba Mountain Revolutionary Base Area.
