The expressway network of China, with the national-level expressway system officially known as the National Trunk Highway System (Chinese: 中国国家干线公路系统; pinyin: Zhōngguó Guójiā Gànxiàn Gōnglù Xìtǒng; abbreviated as NTHS), is an integrated system of national and provincial-level expressways in China.[1][2]
With the construction of the Shenyang–Dalian Expressway beginning between the cities of Shenyang and Dalian on 7 June 1984, the Chinese government started to take an interest in a national expressway system. The first modern at-grade China National Highways is the Shanghai–Jiading Expressway, opened in October 1988.[note 1] The early 1990s saw the start of the country's massive plan to upgrade its network of roads.[1][dead link][3] On 13 January 2005, Zhang Chunxian, China's Minister of Transport introduced the 7918 network, later renamed the 71118 network, composed of a grid of 7 radial expressways from Beijing, 9 north–south expressways (increased to 11), and 18 east–west expressways that would form the backbone of the national expressway system.[2][dead link][4]
By the end of 2020, the total length of China's expressway network reached 161,000 kilometres (100,000 mi),[5] the world's largest expressway system by length, having surpassed the overall length of the American Interstate Highway System in 2011.[6] Many of the major expressways parallel routes of the older China National Highways.[citation needed] By the end of 2022, the total length of China's expressway network reached 177,000 kilometres (110,000 mi).[7]
