With the constant advance of urbanization process,landscape project has extensively developed.

The article introduces the express system of Kunming Main City Area Northeast Ring 2 Rebuilding Extension Project including the structure type,anti-earthquake design,existing bridge rebuilding,durability design and engineering landscape design,which can be referred for the structural design of city elevated bridge projects.

Combining with the method and measures of the practical application of the project,the fine calculation of the complexity region is realized,meet the actual needs of landscape engineer.
