A 25,000-tonne bridge successfully completed a precise millimeter-level rotation after about 80 minutes of steady movement.  The project adopted an unbalanced rotation design with a 1,750-tonne counter weight, setting a new record for the same type of bridge in southern China. With a total length of 144 meters and a width of 42 meters, it rotated 80 degrees counterclockwise and docked precisely with the approach bridge. Equipped with the BeiDou monitoring system, it achieved full-process visualized monitoring during the rotation.
