Recently, Chengxi Expressway, Xiangyi Expressway and Shiyi Expressway ushered in new progress 01Chengxi Expressway
The three expressways of Shanghai-Rong, Jiangnan and Shanghai-Chongqing are connected to form a closed-loop expressway in the outer ring of Yichang City, which efficiently connects with the urban expressway network, further optimizes the urban spatial layout and improves the efficiency of transit traffic.
Xiangyi Expressway
It has promoted the docking of the Hanjiang River and the Yangtze River, the Central Plains and the Three Gorges, and effectively connected the two national-level vertical and horizontal corridors of the Shanghai-Rong Expressway and the Hubei Expressway.
Shiyi Expressway
It is of great significance to promote the linkage development of the tourism resources of "two rivers and three mountains (Yangtze River, Qingjiang, Wudang Mountain, Shennongjia and Wuling Mountain)" in Hubei and Hunan provinces
Presently. Three key highways
Geological drilling work
It's in full swing
According to statistics. Three highways.
The total length of all boreholes.
Approx41983 meters
Equivalent toA marathon full course
The road is underfootThe mountains are rugged, the jungle is dense, and the equipment weighing thousands of pounds is broken into pieces every time it is "moved", and the load is forwardStart the journey again

Geological detailed survey entered the field in mid-July, and a total of 586 boreholes of 21,684 meters were completed. Among them, there are 19 tunnels of 3851 meters, accounting for the proportion；567 17,833 meters of roadbed bridges, accounting for the proportionOn November 21, in addition to the Shazhenxi Yangtze River Bridge, Jiuqixi Bridge, and Zhaxi River Bridge, the field results of the route survey and detailed survey passed the acceptance.
Yichang section of Xiangyi Expressway
Since the start of the geological survey in August, a total of drill holes have been arranged479 pcs, the cumulative footage is reached15000 meters, including 113 roadbeds of 3,024 meters, 308 bridges of 9,705 meters, and 16 tunnels of 2,337 meters.
On October 24, the results of the whole line of regular survey and detailed survey successfully passed the acceptance, marking the projectEnter the construction drawing design stageIt has laid a solid foundation for the substantial start of construction of the project within the year.
Chengxi Expressway (including Nanjinguan Yangtze River Bridge).
After 40 days, a total of 256 holes were drilled on site, with a total of 5,299 meters completed, including 13 Yangtze River bridge sections of 757 meters, with a completion ratio, 146 wiring sections 4542 meters, completion ratio
On December 2, the preliminary survey and preliminary survey results of the Nanjinguan Yangtze River Bridge successfully passed the expert acceptance organized by the Provincial Department of TransportationThe next step will be to carry out the preparation of preliminary design documents.
"Ten lines and three rings" spider webThe construction of the expressway network is acceleratingThe future is just around the cornerStay tuned
