Taiyuan Wusu International Airport (IATA: TYN, ICAO: ZBYN) is an international airport serving Taiyuan, the capital of North China’s Shanxi province.

It is the largest airport in Shanxi and is located about 15 kilometers (9.3 miles) southeast of downtown Taiyuan.

Built in 1939, it has evolved into one of the busiest and most important airports of Shanxi Province, with connections to most major cities within China.

Since March 2006, the airport has undergone an expansion phase with a new terminal at a cost of CNY 1.57 billion, and is capable of serving 6 million passengers a year.

Since this expansion, it has been able to serve as a diversionary airport for Beijing Capital International Airport, and notably performed that function during the 2008 Beijing Olympics.
