Introduction of Yalu River Expressway?

Yalu Expressway starts from Ya 'an, connects with Chengya Expressway, passes through Yingjing, Hanyuan, Shimian and Mianning to Lugu, and connects with Lugu to Xichang Expressway. Zhong Da Consulting consulted various building websites and got information about Yalu Expressway:

Yalu Expressway, also known as Yaxi Expressway, refers to the expressway from Ya 'an to Lugu Town, Mianning County. It is located in Ya 'an City and Liangshan Prefecture in the southwest of Sichuan Province. It is a section of Gansu (Lanzhou)-Yunnan (Mohan) Highway in Sichuan and a section of G5 Beijing-Kunming Expressway, passing through Yucheng District, Yingjing County, Hanyuan County, Shimian County, Luxian County and Mianning County of Liangshan Prefecture.

Yalu Expressway is divided into Ya 'an-Shimian and Shimian-Lugu sections, with a total length of 244 kilometers. 20 12 officially opened on April 29th.

Yalu Expressway is one of the eight inter-provincial highway passages planned by the Ministry of Communications-Lanzhou, Gansu-Mohan Highway in Yunnan. It is the main passage from Sichuan to Yunnan and Kunming, forming the fastest passage from Sichuan to coastal ports in Southeast Asia and South Asia.

Yalu Expressway has nine interchanges: Zishi, Yingjing, Shizi, Jiuxiang, Hanyuan, Shimian, Liziping, Yihai and Mianning.

Yalu Expressway is located in subtropical humid monsoon climate zone with complex meteorological conditions. Rainfall, snowfall, temperature and other meteorological factors change significantly in different areas and at different altitudes: Ya 'an and Yingjing are wet and rainy areas, Hanyuan is dry and rainy areas, Shimian-Lugu is moderate rainfall areas, and Nishan and Tuowu Mountains are seasonally frozen, with fragile ecological environment along the line and great difficulty in environmental protection.

Yalu Expressway is a typical mountainous expressway, passing through Mud Mountain and Tuowu Mountain in Daxiangling at an altitude of more than 3,000 meters, along the Dadu River and Nanya River, and passing through geological disease-prone areas such as coal mine goaf, granite mining area, asbestos tail mining area and debris flow respectively. Passing through the famous active fault zone in China, the earthquake activity is frequent and has the characteristics of high magnitude and intensity; It also crosses the reservoir area of Pubugou Power Station for more than 60 kilometers. The design and construction of deep-buried extra-long tunnels, the design of long-span Gao Qiao in high-intensity earthquake areas, the safe operation of double-helix tunnels and 50-kilometer-long longitudinal slopes, the treatment of adverse geological diseases in active fault areas, environmental and ecological protection and other technical problems are special and typical all over the country and even the world.
