The 4th Ring Road () is a controlled-access expressway Ring roads of Beijing, ring road in Beijing, China which runs around the city, with a radius of approximately from city centre. The total length of the road is . 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.
Already 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 People's Republic of China, the eastern stretch of the 4th Ring Road was opened from Siyuan Bridge to Shibalidian around October 1, 1999. This was the first part of the ring road to be opened as an 8-lane expressway (4 lanes per direction, not including an emergency belt).
The northern part of the 4th Ring Road from Jianxiang Bridge to Siyuan Bridge was converted to an 8-lane expressway in late September 2000. Later that year, the southern part from Shibalidian through to Fengtai District, Fengtai opened to traffic, as was the case with the northwestern part.
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.
When it was opened by 2001, the 4th Ring Road's signs were plagued by inconsistency. Mixing of Hanyu Pinyin and English language, English on the signs confused drivers, but what was most confusing was the exit numbering. It so happened that the ''same exit'' had ''two different exit numbers''—one for each direction of the ring road.
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 Chinese written language, Chinese Hanzi. Some bridge names (e.g. Sihe Bridge) are also getting a name change at the same time.
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 3rd Ring Road (Beijing), 3rd and 5th Ring Road (Beijing), 5th Ring Roads of Beijing, ring roads. Unfortunately, many complain of an information overkill. Signs are now complex enough to hold five ''different'' directions (on some bridges). Meanwhile, the mixing of lowercase and uppercase English in small font sizes is another concern.
On both the 4th Ring Road and the 5th Ring Road, some speed cameras were put into place, along with the general sign changes.
Route
The 4th Ring Road runs within the confines of the city of Beijing, more like a rectangle than a circle. The route travels past: Siyuan Bridge - Chaoyang Park Area - Sihui (Beijing), Sihui - Sifang Bridge - Shibalidian - Dahongmen - Majialou - Yuegezhuang Bridge - Fengtai District, Fengtai Area - Sijiqing Area - Zhongguancun Area - Jianxiang - Asian Games Village (Beijing), Asian Games Village Area - Wanghe Bridge - Siyuan Bridge The entire express road is complete and open to traffic.History

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.Traffic conditions
The portion from Jianxiang to Siyuan Bridge, in both directions, is especially vulnerable to horrible traffic jams. The remainder of the northern and eastern portions are also vulnerable. Apart from the Fengtai District, Fengtai area, the remainder of the 4th Ring Road has a lesser risk of being clogged up by traffic jams.Major exits
Siyuan Bridge, Sihui, Beijing, Sihui, Sifang Bridge, Shibalidian, Majialou, Fengtai District, Fengtai, Yuegezhuang, Zhongguancun, Jianxiang Bridge, Wanghe Bridge.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. Jingcheng Expressway: Connects to the Jingcheng Expressway at Wanghe Bridge (for the time being, only heading for Laiguangying and Chengde). Airport Expressway (Beijing), 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. Jingtong Expressway: Connects to the Jingtong Expressway at Sihui. Jingshen Expressway: Connects to the Jingshen Expressway at Sifang Bridge (only heading for Shenyang). Jingjintang Expressway: Connects to the Jingjintang Expressway at Shibalidian. Jingkai Expressway: Connects to the Jingkai Expressway at Majialou. Jingshi Expressway: Connects to the Jingshi Expressway at Yuegezhuang.Signs
