Amazing Chinese infrastructure! Four bridges rotate synchronously for 90 minutes before 'excellent hand holding'

At 2:00 am on December 2nd, the "throat passage" of Beijing Daxing International Airport Expressway was officially opened, and the main body of the expressway was basically completed.

At 0:30 in the morning, four bridges with a total weight of 10000 tons on three lines started rotating synchronously and docked with the opposite line 90 minutes later.

The 'Three Lines and Four Bridges' all pass through the Beijing Shanghai Railway and the Beijing Shanghai High speed Railway on their way to the new airport. In order to avoid affecting the normal operation of these two busy lines and reduce the occupation of existing land, all three lines adopt the structure of elevated bridges.

The successful transformation of the "Three Lines and Four Bridges" marks the official opening of the "throat passage" of the Beijing Daxing International Airport Expressway, laying the foundation for ensuring its completion and opening to traffic in 2019.
