Client: Yunnan Demeng Expressway Investment & Development Co., Ltd

Location: Puer City, Yunnan Province

Area: 49.172 km 

Work Period: September 2017 – July 2020

Service to Scope : Survey and Design

The Ruili-Menglian Section of the Yanbian Expressway serves as the "border route" in Yunnan's "Five Vertical, Five Horizontal, One Border, Two Rings, and Twenty Links" expressway network. It functions as a trunk road for China’s radiation center toward South and Southeast Asia, a vital international connectivity corridor, key infrastructure for border development, and a major support for Yunnan’s border economic belt.

     Located in mountainous terrain, the project faces challenges including high seismic intensity and a high proportion of bridges and tunnels. China Design Group is responsible for the survey and design of Section SJ8, which spans 49.172 km and is built to dual four-lane expressway standards with a design speed of 80 km/h.

     Leveraging professional expertise and close collaboration, our design team conducted meticulous surveys and developed refined designs. Through mature full-process management and extensive experience, we helped achieve optimal cost-effectiveness within the project budget.
