construction

Chengde is 225 kilometers away from Beijing. Due to the inconvenient transportation, the unique advantages of tourism resources can not be fully exerted. To this end, Chengde City has actively planned expressway projects. After many efforts, on March 26th, 24, the tender for the civil engineering of Beijing-Chengde Expressway was successfully completed, the construction units of 1 blocks were determined, and all the construction agreements, clean government contracts and safety production contracts were signed. After April 5th, various project management departments were set up one after another.

Difficulty

The third-phase project of Jingcheng Expressway, which took two years to build, is located in the northeastern mountainous area of Miyun County, this city, starting from Shayugou in Mujiayu Town, Miyun County, connecting with Jingcheng Phase II, ending at Simatai at the junction of Beijing and Hebei, and connecting with Chengde section of Jingcheng Expressway in Hebei Province, with a total length of 62.7 kilometers. Looking along the expressway, the newly built asphalt road is hidden in the mountains. Beautiful scenery often comes from danger. This winding and magnificent new "Great Wall" is the most difficult section of expressway for survey, design and construction in this city in the past 1 years, and it is also the longest mountain expressway in this city. There are 8 * * * interchanges, 18 bridges and 2 tunnels along the line, of which the tunnel passing through the scenic tourist area of Simatai Ancient Great Wall is 2.2 kilometers long. According to the introduction of Shoufa Group, the third phase of Jingcheng Expressway is a fully-interchanged, fully enclosed and two-way four-lane expressway, in which the subgrade from Shayugou to Simatai is 26 meters wide, with a design speed of 1 kilometers per hour, and the subgrade from Simatai to the city boundary is 24.5 meters wide, with a design speed of 8 kilometers per hour. There are 8 toll stations along the whole line, and each toll station has ETC lanes.
