Its built has an extremely important significance to improve the work structure of national highway and to speed up the economic and social development among cities. The proposed highway of Yanshi Guxian to Huangmangya through the regional landscape which conclude Einon flood alluvial slope, Yiluo River alluvial plain, plain area, Luohe central Loess Hilly Area of Luoyang. The landform is little ups and downs and its fulllength is . According to the standard requirements, bined with the local actual situation, all use the twoway and four lane highway, asphalt pavement. The design speed is 80km/hand the roadbed width is design of the study contents include: firstly, considering traffic volume to determine the number of the toll lanes, and select lines and decide on the topographic map and then road design, design and vertical section design, cross section, bridge and culvert settings. In addition, the roadbed and pavement of this section are also designed.
