Asia's largest underground transportation hub expected to open in 2025

Asia's largest underground transportation hub, Beijing Sub-center Station, will be available for traffic this year.

The station will promote the realization of a "one-hour traffic circle" in the Beijing-Tianjin-Hebei region. It will take 15 minutes to reach the Beijing Capital International Airport; 35 minutes to either Beijing Daxing International Airport or Tangshan city in Hebei province; and one hour to either the Xiong'an New Area or Tianjin's Binhai New Area, according to Beijing Daily.
