The Fourth Nanjing Yangtze River Bridge, the longest suspension bridge in China, as well as the third one in the world, is a two-tower three-span suspension bridge with the main span of 1 418 m. The key construction techniques for the superstructure, including lifting and installation of the cable saddles, erection of the traction system, walkways and main cables, rearrangement of the main cables, installation of the suspender cables and the cable clamps, erection of the steel box girders and wrapping of the main cables, are discussed in detail in this paper. It can provide some references for the construction of the superstructures for the similar suspension bridges in the future.
