Although it is the city's fourth ring road, it is, oddly enough, named the 5th Ring Road.
The 5th Ring Road runs within the confines of the municipality of Beijing. It has an odd twist at the southernmost tip; in order to avoid bumping into the confines of Nanyuan Airport, it has to undergo a major bend at Tuanhe Bridge (团河桥).
Basic Route: Laiguangying (来广营) - Wuyuan Bridge (五元桥) - Yaojiayuan (姚家园) - Yuantong Bridge (远通桥) - Wufang Bridge (五方桥) - Dayangfang (大羊坊) - Yizhuang (亦庄) - Tuanhe (团河) - Xihongmen (西红门) - Langfa (狼垡) - Wanping (宛平) - Yamenkou (衙门口) - Xianghongqi (箱红旗) - Shangqing (上清) - Beiyuan (北苑) - Laiguangying (来广营)
A major traffic jam occurred on March 28, 2005, on the outer ring (counterclockwise direction) 2 kilometres to the south of the interchange with the Jingshi Expressway, when a speeding lorry caused a traffic accident involving six vehicles. The lorry ploughed into five vehicles which were just braking. 
Minimum speed limit of 50 km/h, maximum 100 km/h. Portions of the expressway have maximum limits at 90 km/h.
6 lanes (3 up, 3 down) throughout.
Reduced speeds during rush hour.
