The 4th Ring Road (Chinese: 四环路; pinyin: Sìhuánlù) is a controlled-access expressway ring road in Beijing, China which runs around the city, with a radius of approximately 8 kilometres (5.0 mi) from city centre.[1][2] The total length of the road is 65.3 kilometres (40.6 mi). There are 147 bridges and viaducts that run the length of the Ring Road.
The first section, the northern corridor, was completed in preparation for the 1990 Asian Games. The Ring Road was 'enclosed' in a full circle in June 2001, with standard controlled-access expressway throughout.
Route
The 4th Ring Road is entirely within the city limit of Beijing, and while it is called a ring, the road is shaped rectangularly.
The route travels past:
History
In the early 1990s, the northern stretch of the 4th Ring Road from Zhongguancun to Siyuan Bridge existed as a ring road, albeit with far narrower road conditions and with traffic lights. Only three flyover viaducts—those at Jianxiang Bridge, Anhui Bridge and Siyuan Bridge—existed.
To commemorate the 50th anniversary of the
The northern part of the 4th Ring Road from Jianxiang Bridge to
By June 2001, the entire 4th Ring Road had been converted into an expressway-standard thoroughfare.
In early 2004, the speed limit was reduced to a unified 80 km/h (minimum speed limit: 50 km/h).
In September 2004, the 4th Ring Road underwent a massive sign change. Exit numberings were unified at last—bidirectionally (this was previously not the case).
A new overpass in the northern stretch was put into operation in October 2004, near the Beichen area.
Road conditions
Speed limit
Previously: first lane, min. 80 km/h, max. 100 km/h; second lane, min. 70 km/h, max. 90 km/h; third lane, min. 60 km/h, max. 80 km/h; fourth lane, min. 50 km/h, max. 80 km/h; auxiliary road, uniform max. speed limit of 70 km/h. Readjusted in 2004 so that all lanes have a uniform min. speed limit of 50 km/h and a max. speed limit of 80 km/h; aux. road max. speed limit of 70 km/h remains unchanged.
Tolls
This express road does not charge tolls.
Lanes
8 lanes (4 in each direction) throughout.

.Service areas
No full-scale service areas exist; however, filling stations (gas stations) are plentiful in number.
Connections
Badaling Expressway: Connects to the Badaling Expressway at Jianxiang Bridge.
Airport Expressway: Connects to the Airport Expressway at Siyuan Bridge (only heading for the airport).
Projected Jingping Expressway: Would most likely connect at Dongfeng North Bridge.
Jingjintang Expressway: Connects to the Jingjintang Expressway at Shibalidian.
Signs
When it was opened by 2001, the 4th Ring Road's signs were plagued by inconsistency. Mixing of
Beijing authorities had three years' lapse before they dealt with the problem. Old signs were progressively replaced by newer signs which had standardised English and, finally, a new exit numbering system was in place. A sketch map of each exit, formerly only for expressways and isolated spots, was also introduced along with the new sign numbering.
Another change was the use of traffic sign language to signal traffic regulations instead of relying completely on
The project was somewhat Herculean since 441 signs were to be replaced. Of those, exit and entrance signs formed 202 signs; other, mainly larger-sized signs, formed the remaining 239 signs. Earlier in the summer of 2004, similar measures for the 5th Ring Road (which had an absent-to-chaotic exit numbering system) were announced.
In a show of speed, within the first 100 hours, new exit numberings were put up for almost all of the western stretch of the 4th Ring Road (despite new/old signs being alternated on a different stretch of the ring road).
Reaction to the new signs are mixed. There is a definitive plus side: the exits are now matched with their equivalent exit/bridge names on the
On both the 4th Ring Road and the 5th Ring Road, some speed cameras were put into place, along with the general sign changes.
