The '''3rd Ring Road''' ({{zh|t=北京三環路|s=北京三环路|p=Sān Huán Lù}}) is a {{convert|48.2|km|adj=on|sp=us}}-long [[Ring Roads of Beijing|city ring road]] that encircles the [[Beijing central business district|city center]] of [[Beijing]].<ref>{{cite web|url=https://jtw.beijing.gov.cn/xxgk/xwfbh/201912/t20191209_1007441.html|date=2016-10-14|title=西北三环道路大修主体完工|quote=三环路是北京市城区交通主干线，发挥着贯通区域交通、疏解核心区交通流量的重要作用，全长48.2公里。上次大修时间为2003年，距今已13年。}}</ref><ref>{{cite web|url=https://www.beijing.gov.cn/renwen//jrbj/csjz/201807/t20180711_1874261.html|date=2018-07-11|title=一圈“新三环”10月底亮相|quote=三环路始建于上世纪70年代初期，上世纪90年代经快速化改造后形成环路，途经海淀、朝阳、丰台三区，全长48.2公里，是北京市重要环城快速路，是中心城区交通主动脉之一。}}</ref><ref>{{cite web|url=https://zjw.beijing.gov.cn/bjjs/gcjs/zczjxx/304937/355433/index.shtml|title=北京全长约48公里的三环路开始全面施工改造|date=2002-12-30}}</ref>

When Beijing first became the capital of the [[People's Republic of China]], the road existed only in segments encircling the northern, eastern, and southern parts of the city. At the time, its segments were known as Beihuan (North Ring), Donghuan (East Ring), and Nanhuan (South Ring), respectively. The 3rd Ring Road was finally finished in 1994 with the completion of the western segment. There are 52 flyovers, including [[Sanyuan Bridge|Sanyuanqiao]], which links it to the [[Airport Expressway (Beijing)|Airport Expressway]]. The speed limit is a uniform 80 km/h.

The ring road runs through the busy [[Beijing Central Business District|CBD]] section in the east through Panjiayuan and Fenzhongsi, linking up with the [[Jingjintang Expressway]]. It continues south toward [[Muxiyuan]] and [[Yuquanying]], linking up with the [[Jingkai Expressway]]. It then proceeds west, linking up with the [[Jingshi Expressway]] before running into the western segment, which is linked with the Wukesong residential area, TV broadcasting centers, and, in the northwest, [[Zhongguancun]] IT zone. The northern segment is equally busy, running through Beitaipingzhuang, with links to the [[Badaling Expressway]] and the [[Jingcheng Expressway]].

The 3rd Ring Road is notorious for its [[traffic jams]]. The eastern segment, which runs through Beijing's [[central business district]] (CBD), is regularly gridlocked during rush hour. The interchanges of this segment are modified [[diamond interchange]]s, consisting of openings of the road barrier on the right that separates the main lanes from the frontage roads. These interchanges can often back up traffic since they cannot easily handle the huge traffic volumes of Beijing. The situation is often worsened by the bus stops that are located right adjacent to the exits.

== Location ==
The 3rd Ring Road is {{convert|2.5|km|sp=us}} from the [[2nd Ring Road]] and {{convert|5|km|sp=us}} from the [[Beijing central business district|city center]]. The 3rd Ring Road goes through mostly residential and some commercial areas (except for the CBD) that were created during Beijing's first wave of rapid expansion.

== Surface conditions ==
{{More citations needed|section|date=November 2022}}
Until 2003, the entire 3rd Ring Road was very bumpy, and trips were very unpleasant. Following the renovation of the [[2nd Ring Road]] in 2001, a similar project was conducted in 2003 and the road surface has been much smoother since then.

== Beijing Subway ==
[[Line 10 (Beijing Subway)|Line 10]] of the Beijing Subway has been constructed under the eastern segments of the 3rd Ring Road and was completed in 2008. [[Line 12 (Beijing Subway)|Line 12]] has been constructed under the northern segments of the 3rd Ring Road and was completed in 2024.<ref>{{cite web|url=https://www.bjnews.com.cn/detail/1734230905129973.html|title=“地下北三环”今起开通：北京地铁12号线设13座换乘站|trans-title="The underground North 3rd Ring Road" opened today: Beijing Subway Line 12, with 13 transfer stations|quote=从今天（12月15日）起，地铁12号线（四季青桥—东坝北）开通运营，这条线路因为走向主要沿北三环东西向铺设而被称为“地下北三环”。此次开通四季青桥—东坝北站段，运营里程27.5公里，共设20座车站，均为地下站，其中换乘站13座}}</ref>

The '''Capital Airport Northern Expressway''', officially numbered '''S28''', is an 11.29 km toll road extension that runs from [[G45 Daqing–Guangzhou Expressway]] (formerly Beijing-[[Chengde]] Expressway) to the [[Beijing Capital International Airport]] in [[Beijing]], [[China]]. It was opened in September 2006.<ref>(Chinese) [https://web.archive.org/web/20061023111020/http://news.xinhuanet.com/life/2006-09/29/content_5151430.htm 京承高速二期机场北线高速全线通车/图京华时报] Sept. 29, 2006</ref> The opening of this road has helped to alleviate traffic on the [[Airport Expressway (Beijing)|Capital Airport Expressway]], which had been the sole highway link to the airport. The Capital Airport Northern Expressway allows drivers from [[Zhongguancun]] and points north and west of the city to head north first on Jingcheng Expressway before going directly east to the airport, instead of having to go east on the [[4th Ring Road]] to get on the Capital Airport Expressway, where traffic is often clogged near the [[Siyuan Bridge]].

The '''Capital Airport Expressway''' ({{lang-zh|c=首都机场高速公路|p=Shǒudū Jīchǎng Gāosù Gōnglù}}), officially the '''S12''', is a [[controlled-access highway]] in [[Beijing]], [[China]], which links central Beijing to the [[Beijing Capital International Airport]]. It is just under 20 km in length.<ref>{{Cite book |last=Waters |first=Harry J. |url=https://books.google.com/books?id=Ld4_rRT355AC |title=China's Economic Development Strategies for the 21st Century |date=1997 |publisher=Greenwood Publishing Group |isbn=978-1-56720-095-9 |pages=135–136 |language=en}}</ref>

Opened in 1993, the expressway links [[Sanyuan Bridge]] (Sanyuanqiao) on the northeastern [[3rd Ring Road (Beijing)|3rd Ring Road]] to Beijing Airport. Another expressway, the [[2nd Airport Expressway]], was built in 2008 prior to the Beijing Olympics to serve traffic from the city to the airport.

==Route==
The Airport Expressway runs entirely within the confines of the municipality of Beijing.

Basic Route: Beijing ([[Sanyuan Bridge]] - Siyuan Bridge - Beigao - Xiaotianzhu - [[Beijing Capital International Airport]])

==History==
The expressway opened on September 14, 1993, following a year-long construction effort which began on July 2, 1992. Previously, all traffic used the old Airport Road ([[China National Highway 101|G101]]), which was tested to the limit in the early 1990s.

This expressway has slashed driving time to the airport from the previous hour (using the old airport road) to just around 15 minutes. It is convenient and traffic is usually smooth.

===Extension into the 2nd Ring Road===
A 2.5 km stretch of expressway links [[Sanyuan Bridge]] on the [[3rd Ring Road (Beijing)|3rd Ring Road]] to the area between [[Dongzhimen]] and Xiaojie Bridge (小街桥) on the [[2nd Ring Road (Beijing)|2nd Ring Road]]. Construction started in 2004; it was finished in 2006.

==Alternate routes==
Further approach routes to the airport were built in the first decade of the 21st century. The [[Northern Airport Line]] (机场北线), completed between 2005 and 2006, connected the [[Jingcheng Expressway]] with the northern part of the airport, to form a northern approach route. The route commences at Lutong, just over halfway between the [[5th Ring Road]] and the [[6th Ring Road]], on the [[Jingcheng Expressway]]. In 2008, another route, the [[2nd Airport Expressway|Capital Airport 2nd Expressway]], was built between the eastern 5th Ring Road and the airport in time for the Beijing Olympics. Both routes have significantly alleviated traffic to the airport from the city proper.

==Road conditions==
===Speed limit===
Leftmost lane: minimum 100 km/h, maximum 120 km/h. Other lanes: minimum 60 – 80 km/h, maximum 100 km/h.

===Tolls===
The toll collection on the Airport Expressway has a contentious history. Construction was funded by the government using a bank loan in 1993, and residents began to dispute the rationale for the toll collection several years after the road was completed, doubting that the loan was paid off and that most of the revenue was actually used to pay back the loan. Despite these inquiries and complaints, the local government continued to collect tolls. The toll collection rights were eventually sold to a public corporation, the Capital Development Corporation, and the time of toll collection was lengthened by 30 years.<ref>{{Cite book |last1=Chen |first1=Xueming |url=https://books.google.com/books?id=0l11CQAAQBAJ |title=Building Resilient Cities in China: The Nexus between Planning and Science: Selected Papers from the 7th International Association for China Planning Conference, Shanghai, China, June 29 – July 1, 2013 |last2=Pan |first2=Qisheng |date=2015-05-20 |publisher=Springer |isbn=978-3-319-14145-9 |pages=326 |language=en}}</ref> The central government's general accounting office investigated and found that in the 14-year period (up to 2005), the total toll revenue was over 3 billion yuan; this was much higher than the original investment amount, 1.2 billion yuan. Under pressure, the local government lowered the toll from 15 to 10 yuan.

CNY 0.5/km as of [[5th Ring Road]] intersection for sections south of the toll gate. Entire stretch from [[Sanyuan Bridge|Sanyuanqiao]] to [[Beijing Capital International Airport]] costs CNY 5 (price for small passenger cars). As of June 2011, the Airport Express is free of charge into the city, but retains the CNY 5 fare toward the airport.<br />
'''Note:''' For frequent users, a sensor-style Express Transit Card is available.

===Lanes===
6 lanes (3 up, 3 down) uniformly.

===Traffic===
Good during the day. Mild traffic jams during rush hour, mostly in the southern section of the road near Beijing.

==Major exits==
NE [[2nd Ring Road]], NE [[3rd Ring Road (Beijing)|3rd Ring Road]], NE [[4th Ring Road]], [[Dashanzi]], NE [[5th Ring Road]], [[Beigao]], [[Xiaotianzhu]], [[Beijing Capital International Airport]]

==Service areas==
None on the expressway. The [[Weigou]] exit has a gas station close to it (on the way back to [[Beijing]]).

==Connections==
[[Ring roads of Beijing]]: Connects with the NE [[2nd Ring Road]] between [[Dongzhimen]] and Xiaojie Bridge (小街桥), NE [[3rd Ring Road (Beijing)|3rd Ring Road]] at [[Sanyuan Bridge]], the NE [[4th Ring Road]] at Siyuan Bridge, and the NE [[5th Ring Road]] at Wuyuan Bridge.
