　　The Dashuying Interchange Reconstruction and Expansion Project is a crucial node in the Second Ring Road rapid transformation project. After the renovation, the Dashuying Interchange will increase from 2 to 5 layers. The steel box girder ramps are located on the 4th and 5th layers, with a maximum installation height of 31 meters and a single weight of 140 tons. The bridge decks on the lower 3 layers have been completed, leaving only a 1-meter-wide gap between the two bridges for temporary scaffolding, requiring a 400-ton crawler crane for installation.
