Yongwu-Heading up into the Interior
It will play a vital role in the development of the infrastructure and the economy of this rough mountainous region. The design institute used CARD/1 for this challenging project.
The entire motorway has four lanes. The standard cross-section RQ25.5 together with a design speed of 80km/h was used for 74km and 121km were designed using the standard cross-section RQ26 with a design speed of 100km/h.
Despite the quick design process, the design quality never suffered.
- A total volume of 30,355,000m3 had to be moved.
- The asphalt surface is 3,255,000m2 and the concrete surface area is 512,000m2 in size.
- Altogether, the 130 bridges are 37km long. 339 culverts for rivers and drainage facilities totalling a length of 19km had to be calculated. What’s more, 29 tunnels with an overall length of 29km, 11 intersections and 26 junctions with a total bridge length of 2.3km were part of the project.
- 230 crossing facilities for pedestrians have been planned, 91 of which are below ground and 8 of which are footbridges with a total length of 546m. The safety facilities cover the entire length of the motorway.
- 29,636 plans were produced for the design.
- The construction costs are estimated to total approx. 12bn RMB, equivalent to 1.2bn Euro.
