The Jingzhang Expressway (Chinese: 京张高速公路; pinyin: Jīngzhāng Gāosù Gōnglù) is a 79.2 kilometres (49.2 mi) expressway in China connecting Beijing and Zhangjiakou. Construction began in 1998 and finished November 16, 2002. The expressway's name comes from the combination of one-character Chinese abbreviations for Beijing and Zhangjiakou (Beijing—Jing, Zhangjiakou—Zhang).
It is a part of the Jingda Expressway from central Beijing to Datong, in Shanxi province, which was built to reduce traffic on the increasingly congested China National Highway 110, which runs from Beijing to Qingtongxia.
The Jingzhang Expressway has shortened the driving time between Beijing and Zhangjiakou from over three hours to two hours. Its construction is a part of broader goals to improve the road network structure in Hebei Province, stimulate the economy along the route, and promote the economic development of the Zhangjiakou area.
