By the end of 2023, there are 200 ordinary national highways in the mainland, with a total mileage of more than 265,000 kilometers, and the dense network of ordinary national highways will closely connect various cities in the mainland, just like the capillaries of the human body, ensuring the efficient, fast and convenient circulation of people and materials between various cities in the mainland, and playing an irreplaceable and important role in promoting the development of the mainland's economy.
The two road network systems of ordinary national roads and national highways constitute the national roads of the mainland, both of which start with the letter G. Ordinary national highways are generally numbered in the form of G+3 Arabic numerals (i.e. GXXX) and are pronounced as XXX national highways (e.g., G318 is pronounced as 318 national highways).

This series will focus on China's ordinary national roads, and introduce them in detail from three aspects: basic information, provinces and cities passed, and value significance. At present, the mainland plans to build a total of 200 ordinary national highways. These 200 ordinary national roads are divided into four categories: 12 capital radiation lines, 47 north-south longitudinal lines, 60 east-west horizontal lines, and 81 liaison lines.
In this issue, we will introduce: G352 Zhangjiajie - Qiaojia Ordinary National Highway [Zhangqiao Line]
Basic Information

Value significance
The Zhangqiao Line starts in Yongding District, Zhangjiajie City, Hunan Province, and ends in Qiaojia County, Zhaotong City, Yunnan Province. The ordinary national highway is an important national passage connecting Hunan Province and Yunnan Province, constructing the transportation artery of important cities in the east-west direction of the middle reaches of the Yangtze River and the Yunnan-Guizhou Plateau (mainly including Zhangjiajie, Xiangxi, Tongren, Zunyi, Luzhou, Zhaotong, etc.), and building a bridge connecting the east and west of the middle reaches of the Yangtze River and the Yunnan-Guizhou Plateau. At the same time, Zhangjiajie can not only communicate Qiaojia through the Zhangqiao line, but also through other ordinary national roads in the Qiaojia area, and travel to other parts of the country at high speed and effectively, which plays a vital role in strengthening the communication between Zhangjiajie and Qiaojia and even the rest of the country.
