Successfully turning over a double-track bridge weighing tens of thousands of tons, "flying across" the Chengdu-Chongqing Railway.

On the morning of January 28th at 7 o'clock, the "T-type" double-span rotary bridge with a total weight of about 11,200 tons slowly rotated under the drive of four sets of hydraulic systems. After 100 minutes of clockwise synchronous rotation of 80.8 degrees, it accurately reached the designed bridge position, successfully crossing the Chengdu-Chongqing Railway, marking a significant breakthrough in urban road construction in Rongchang District, Chongqing.
