Beijing section of Jingxin Expressway
Jingxin Expressway (Fifth Ring Road-Sixth Ring Road) project is the starting point of G7 Jingxin Expressway. The project is located 3km west of G6 Beijing-Tibet Expressway, starting from Yue Quan Road South. The highway is a three-way, three-lane and six-lane continuous parking zone with a design speed of100 km/h. There are 8 interchanges, 8 separated interchanges, 5 river-crossing bridges and 3 passages. Jingxin Expressway (Fifth Ring Road-Sixth Ring Road) started in June 2009 +065438+ 10. 2065438+officially opened to traffic in May 2004. Among them, Shangdi Cable-Stayed Bridge is the key control project of Beijing-Xinjiang Expressway (Fifth Ring Road-Sixth Ring Road Section) and the longest span bridge in North China. The total length of the bridge is 3km, the length of the main bridge is 5 10/0m, the height of the main tower is 99m, and there are 88 stay cables on it, of which the longest cable is 223m and the maximum cable weight is 27 tons. Incremental launching method operation used in construction is the heaviest jacking operation in China at present. Because the beijing-baotou railway on Shangdi Bridge, the subway 13 line and the planned beijing-zhangjiakou intercity railway and the subway 13 line form an included angle of 15 degrees, the included angle is small, and the span of a single tower reaches 230 meters. In order not to affect the operation of railways and subways, and due to the lack of construction land, Shangdi cable-stayed bridge did not adopt conventional construction technology. After many studies and discussions by the expert group, incremental launching method operation and jacking were finally adopted.

The branch lines are 1 bridge and 1 small bridge. The total investment of the project is 6 15899208 yuan, of which the environmental protection investment is 654338+04394 yuan.
Inner Mongolia section of Jingxin Expressway
On the morning of April 27th, 20 1 1, the construction of Han Jiaying-Hohhot section of G7 Jingxin Expressway was officially started, with an estimated total investment of about 156 billion yuan. This is another expressway from Inner Mongolia to Beijing after G6 Beijing-Tibet Expressway.
The route of this project starts from Han Jiaying, Xinghe County, Wulanchabu City, Inner Mongolia, and connects with the Shanxi section of the proposed Jingxin Expressway (Beijing to Urumqi, Xinjiang), passes through Lamaying, Zhang Hao, Bazhong Yao and their subordinate camps, and ends at Baoheshao Interchange in Hohhot, and connects with the completed Hohhot Ring Expressway and the completed Hubao Expressway (G6), with a total length of about 265,438+02km. The whole line adopts the standard construction of two-way six-lane expressway, with a subgrade width of 33.5m and a design speed of100km. The total planned construction period of the project is 3 years.
The Han Jiaying-Hohhot project of Jingxin Expressway is a part of G7 Jingxin Expressway. Jingxin Expressway starts from Beijing, passes through six provinces including Beijing, Hebei, Shanxi, Inner Mongolia, Gansu and Xinjiang, and ends in Urumqi, with a total length of about 2,760 kilometers.
Beijing-Xinjiang Expressway is an important part of the national expressway network. After the completion of the whole line, the distance between Xinjiang and Beijing will be shortened by about 1000 km compared with the existing highway passage, which will divert vehicles from western provinces and regions to some extent, effectively relieve the traffic pressure of Beijing-Tibet expressway, and achieve remarkable social benefits.
Gansu section of Jingxin Expressway
G7 passes through Mazongshan Town, Subei County, Jiuquan City, Gansu Province, starting from Baigeda (Menggan boundary), connecting with the proposed Helin-Baigeda Expressway (Kan Moun boundary) in Inner Mongolia, passing through Mazongshan Town, ending at Mingshui (Gan New Territories) and connecting with the newly-built Mingshui (Gan New Territories)-Hami Expressway, with a total length of 137 km. The whole line adopts the standard of two-way four-lane expressway, the design speed is 120km/h, and the connecting line from Mazongshan Town to Qiaowan is about147km, and the standard of third-class highway is adopted. The estimated total investment of the project is about 665,438+300 million yuan. At present, the construction is about to be completed. At that time, a Jiuhang Expressway will be introduced from Suzhou District of Jiuquan as an important liaison section of Jingxin Expressway.
After the completion of the project, the national expressway network will be improved, the traffic conditions in the north of Jiuquan will be improved, the development of the Mazongshan border port in Jiuquan will be promoted, the exchanges between Jiuquan and Xinjiang, Inner Mongolia, Mongolia and Qinghai will be promoted, and an additional travel passage will be provided for the Hexi Corridor to go directly to Beijing.
