The Airport Expressway (Chinese: 机场高速公路; pinyin: 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.
Opened in 1993, the expressway links Sanyuanqiao on the northeastern 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.
The Airport Expressway runs entirely within the confines of the municipality of Beijing.
Status: The entire expressway is complete.
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, 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.
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, 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.
Leftmost lane: minimum 100 km/h, maximum 120 km/h. Other lanes: minimum 60 – 80 km/h, maximum 100 km/h.
CNY 0.5/km as of 5th Ring Road intersection for sections south of the toll gate. Entire stretch from 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.
Note: For frequent users, a sensor-style Express Transit Card is available.
6 lanes (3 up, 3 down) uniformly.
Good during the day. Mild traffic jams during rush hour, mostly in the southern section of the road near Beijing.
None on the expressway. The Weigou exit has a gas station close to it (on the way back to Beijing).
