History
The expressway in 2006

The expressway was initially a section of the Zhengzhou–Xuchang Expressway, which was opened in the mid 1990s as a section of the Beijing–Zhuhai Expressway (Jingzhu Expressway, the G030 expressway then). On 1 October 2004, with the completion of the Xinxiang–Xuedian section of the Jingzhu Expressway, this expressway was dedicated to serve as a link between Zhengzhou city center and Zhengzhou Xinzheng International Airport and was re-designated as S1 in Henan's expressway system.

During 2014-2016, the expressway underwent a renovation project, which widened it from 4 lanes to 8 lanes.[1][2]

Route

The S1 expressway starts at the interchange of Zhongzhou Avenue and Longhai Expressway as an eight-lane controlled-access expressway. It then heads southeast, intersecting with Hanghai E. Road and South 3rd Ring Road before becoming a tolled expressway at Zhengzhou South Toll Station. It meets G3001 Zhengzhou Ring Expressway near Xiangyunsi, and then runs in parallel to G4 Beijing–Hong Kong–Macau Expressway just to its west. At Airport exit, it connects to Yingbin Elevated Road, a 1.48 kilometres (0.92 mi) long elevated expressway going directly to Zhengzhou Xinzheng International Airport. S1 continues south for about 2 kilometres (1.2 mi) as a four-lane expressway, before it joins G4 Beijing–Hong Kong–Macau Expressway near Xuedian at its southern terminus.
