On November 23, the first steel beam was successfully erected on the north main tower of the G3 Tongling Yangtze River Highway and Railway Bridge, which opened the prelude of the steel beam erection on the north side of the bridge。

　 The world's first double-deck cable-suspension bridge with a main span of 988 meters。The steel beam of the main bridge is divided into three parts: cable-stayed section, suspension section and cable-stayed suspension cross section。The stiffness of steel beams varies greatly due to different stress systems, and it is difficult to control and close the lines。Total bridge steel beams 6.660,000 tons, divided into 59 segments, the largest segment weight of about 1600 tons。The steel beams erected this time are Z0-Z1 sections, 14 meters long, 35 meters wide and 13 meters high.5 meters, weighing 1,230 tons。

　 "After careful deployment and careful preparation, the erection of the first steel beam was 3 days ahead of the construction schedule.。Ren Yinliang, deputy manager of G3 Bridge Project Department of China Railway Bridge Bureau，The steel beams were lifted by a 1,600-ton beam crane from a river barge to the lower beam of the 43-meter-high main tower，Precise splicing with guide beam，Then the spliced steel beam segments and the whole beam hoisting crane are pushed to the side span direction，Then the beam crane moves towards the main span position to the beam position to continue lifting the steel beam，So the cycle until the side auxiliary span steel beams are all installed。
