G4501 Beijing 6th Ring Expressway

The 6th Ring Road runs within the confines of the municipality of Beijing.

Basic Route: Liuyuan Bridge - Liqiaozhen - Sanhui Bridge - Zhangjiawan - Majuqiao - Huangcun - Liangxiang - Mentougou - Zhaikou/Wenquan - Xishatun - Gaoliying - Huosiying - Liuyuan Bridge

It is on the outer fringes of Beijing, and even beyond Beijing Capital International Airport. The expressway ring road is the only one to link with the equally remote Tongyan Expressway.

As early as 2000 or 2001, the southeastern stretch from Sanhui Bridge (interchange with the Jingha Expressway) through to Majuqiao (interchange with the Jingjintang Expressway) was put into operation. The route was first referred to as the projected 2nd Expressway Ring Road, much like the 5th Ring Road was once referred to as the 1st Expressway Ring Road; however, that name was abandoned in favour of the present-day 6th Ring Road.

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 public.

Another 43 km of the expressway ring road opened 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). They were slated for a November 2004 opening. In the first case, the expressway was opened on December 20, 2004, at 14:00 local time, with over a month's delay. The entire road was opened in 2010.

To re-connect several break-of-roads in MC region, Beijing Municipality government decided in 2019 that part of eastern 6th Ring, approximately 16 km, will be widen from 4-lane bidirectional to 6-lane, of which the middle 9.2km section will renovate as an underground section.[4] After renovation, the on-ground sections will re-construct as a high line park. In September 2020, the biggest tunnel boring machine in China has built in Changsha to join the renovation works.[5]

• Badaling Expressway: Xishatun.

At a distance of 20 kilometres from the centre of town, the expressway covers a much larger distance than the inner ring roads. Equally large is the distance between two points.

For example, the distance between Jingtong Expressway to Jingshen Expressway is approximately 2 kilometres on the 4th Ring Road. It expands to nearly 4 kilometres on the 5th Ring Road. On the 6th Ring Road, 10 kilometres elapse from one expressway to the other—and the Jingtong to Jingshen Expressway (on the 6th Ring Road, the Jingha to Jingshen Expressway) is one of the shortest distances between expressways in Beijing.

Anything up to 30 - 35 kilometres can lapse between the Jingcheng Expressway and the Jingha Expressway.

For most people, travel on the 6th Ring Road is extremely rare. Although, strictly speaking, it is still on the perimeters of city limits, this is one massive ring road for a motorist to travel around.
