Ten thousand-ton bridge completes 'air swivel'

At 2:18 am on Wednesday, the box girder of No. 8 pier of Qiqihar City-Civil Aviation Road Overpass Bridge in Heilongjiang Province completed a counterclockwise rotation.

This is a concrete continuous beam structure bridge with a large span and heavy tonnage in a severely cold area across China.
