Sanyuan Bridge

Sanyuanqiao, or Sanyuan Bridge (simplified Chinese: 三元桥; traditional Chinese: 三元橋; pinyin: Sānyuán Qiáo) is a major overpass on the northeastern stretch of Beijing's 3rd Ring Road.

The overpass links three major passageways in Beijing and the complex structure made it a speciality on its own in its first days.

The simple complexity of the overpass was tempting to tamper with, but in the 1990s, the temptation was too much (caused by excess traffic): another portion of a flyover was built for vehicles heading from the eastern 3rd Ring Road to interlink directly with the Airport Expressway.

Line 10 and the Airport Express stop at Sanyuanqiao Station.

The replacement was constructed as a single prefabricated piece and installed in place of the original.
