The Aizhai Bridge is the longest suspension bridge crossing a canyon in the world. A novel pylon–girder detached suspension structure was first adopted in the design of the Aizhai Bridge, which provided a new concept for the design of suspension bridges. Moreover, the application of a high-performance carbon fiber rock anchor system in the bridge provided a new method for applying high-performance carbon fiber materials in engineering structures. In addition, the construction method of the girder-conveying track cable technique proposed for the Aizhai Bridge successfully solved the problem of the erection of the stiffening girders of long-span suspension bridges in mountainous areas. This study mainly introduces the design method, the application of new materials, and the advanced construction technologies of the Aizhai Bridge.
