The Jingzhang Expressway (京张高速公路, Hanyu Pinyin: Jīngzhāng Gāosù Gōnglù) is an expressway in China which links Beijing to Zhangjiakou. It forms part of the Jingda Expressway from central Beijing through to Datong in Shanxi province.

Previously, traffic used China National Highway 110, which used to be clogged up (at times) with traffic. With the traffic situation as it is, and with the onslaught of more traffic, work on the expressway started in 1998, culminating in the completion of the entire expressway on November 16, 2002. The entire length of the expressway is 148.2 kilometres.

The Jingzhang Expressway gets its name by the combination of two one-character Chinese abbreviations of both Beijing and Zhangjiakou (Beijing—Jing, Zhangjiakou—Zhang).

The Jingzhang Expressway runs within Hebei province, although the very beginning of the expressway is in Beijing municipality. For reference, the segment after the Beijing City Limits Toll Gate, heading toward Zhangjiakou, is considered the Jingzhang Expressway.

Basic Route: Badaling Expressway - Donghuayuan - Huailai - Xiahuayuan - Zhangjiakou

The entire expressway is complete and open to traffic. The expressway passes through a bridge over the Guanting Reservoir.

The expressway was created in segments, starting in Hebei. The difficult part was how to get it across the Guanting Reservoir. Previously, traffic was supposed to make a detour, so as not to create a bridge across the reservoir. However, in the end, a bridge across the Guanting Reservoir was built and the expressway's total distance was thus shortened.
