The renovation and expansion of the Zhangjiakou Ningyuan Airport were completed on Saturday, according to CCTV News, meaning that Zhangjiakou in north China's Hebei Province is one step closer to be ready for the 2022 Winter Olympics that will be hosted by Beijing.

The project began in September 2018 with a total investment of about 1.3 billion yuan (about 187 million U.S. dollars), including building new terminal buildings, aprons, and taxiways along with new intelligent visual support systems and air traffic control project.

By Saturday, the installation of the steel structure main body for the new 14,000-square-meter T2 terminal had been finished. Construction of the new communication route and taxiway are completed and meet the terms of use. The runway extension line has been finished and put into use.

The whole project is expected to be completed and put into a test run by the end of 2019.

Li Hui, head of the China Railway 18th Bureau's Zhangjiakou Airport Reconstruction and Extension project, told CCTV News that the renovation and expansion will add another 11 parking spaces to the airport (from three to 14) and increase its annual passenger throughput from 300,000 to one million.

Zhang Jiakou will account for 76 competition venues and supporting infrastructure projects for the 2022 Winter Olympics and China plans to invest 32.8 billion yuan (about 4.73 billion U.S. dollars) for them. So far, 73 projects have begun and six of them have been finished. The remaining ones are expected to be completed by the end of August 2020 except the temporary construction projects implemented by the Beijing Organizing Committee for the 2022 Olympic and Paralympic Winter Games.
