Expressway in Beijing and Hebei, China

The Jingzhang Expressway is a 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.

The Jingzhang Expressway is part of the Jingda Expressway and a part of the China National highway system, a network of trunk ways across mainland China. It stretches from the Beijing City Limits Toll Gate to Zhangjiakou, crossing through locations such as the Guanting Reservoir. While the expressway starts in Beijing, the majority of it runs within Hebei province. The basic route begins at Badaling Expressway; goes through Donghuayuan, Huailai, and Xiahuayuan; and terminates at Zhangjiakou.

The expressway was created in segments, starting in Hebei. The challenge was how to cross the Guanting Reservoir. Initial plans avoided bridges and instead routed traffic around the reservoir. In the end, a bridge across the Guanting Reservoir was built, shortening the expressway's total distance. The Jingzhang Expressway's final segment—linking it to the Badaling Expressway—was completed in November 2002. As of that moment, traffic could flow directly from Beijing through to Zhangjiakou in the form of a direct expressway. Previously, traffic entered the expressway bound for Zhangjiakou only at the Tumu toll gate (later disused), from Beijing.

Most of the expressway has a speed limit of 110 km/h. Hillier terrain and the Guanting Bridge have a lower speed limit of 80 km/h. Speed checks are rare.

The entire stretch charges tolls. The toll system is not networked.

The expressway has four lanes (two up, two down) throughout.

Surface conditions are moderately good.

Traffic conditions to Zhangjiakou from Beijing are better than those in the opposite direction.

Major exits from the expressway are at Donghuayuan, Huailai, Jimingyi, Xiahuayuan, and Zhangjiakou.

The Guanting Service Area is next to the Guanting Bridge.

The expressway becomes Badaling Expressway 60 km from Beijing. After exit no. 5, the Jingzhang Expressway spins off to the right; continuing straight ahead leads to Datong in Shanxi province via the Xuanda Expressway instead.
