of Beijing, and runs almost directly past the Beijing North railway station and Beijing railway station. Prices of real estate inside the ring road are considerably higher than other parts of the city. The 2nd Ring Road of today is part of an extended ring road which takes the southern route through Zuo'anmen and Caihuying instead of Qianmen Road, just south of Tian'anmen. Its southernmost part between Jianguomen and Fuxingmen appears "squashed" outwards. The 2nd ring is directly connected to the Airport Expressway and Badaling Expressway. 3rd Ring Road The 3rd Ring Road was built in the 1980s and completed in the 1990s. It is by no means peripheral, as it passes through Beijing's Central business district and diplomatic communities (Dongzhimenwai / Liangmaqiao, Jianguomenwai). It is directly interlinked with numerous expressways—the Jingcheng Expressway, the Jingshi Expressway, the Jingkai Expressway, and the Jingjintang Expressway. 4th Ring Road The 4th Ring Road was completed in 2001, around from the center of Beijing.
