The expressway ringroad is a provincial-level road in Beijing municipality.
All of Beijing's expressways, except for the Jingha Expressway, are interlinked with the 5th RingRoad.
By mid-2003, half of the ringroad was open, from the western end connecting the West Chang'an Avenue to the interchange in the southeast with the Jingjintang Expressway.
By 2002, a road section starting in Xishatun (interchange with the Badaling Expressway) through to Sanhui Bridge, as well as a stretch from Majuqiao through to Huangcun/Shuangyuan Bridge (interchange with the Jingkai Expressway), were complete and opened to the general motoring public.
Another 43 km of the expressway ringroad is opening behind schedule (the portion linking it up with the Jingshi Expressway and ultimately ending in Liangxiang in December 2004 and the section from the Badaling Expressway to Wenquan/Zhaikou in Mentougou in early January 2005).
On the 6th RingRoad, 10 kilometres elapse from one expressway to the other -- and the Jingtong to Jingshen Expressway (on the 6th RingRoad, the Jingha to Jingshen Expressway) is one of the shortest distances between expressways in Beijing.
