Research purposes:Through the analysis of the main influence factors，including the use of existing road facilities like interchanges，bridge and pavement，the demolition conditions and the metro colineation，and through the research on the reconstruction plan of the plane，vertical，horizontal and interchange roads，the primary discussion is made on the control condition，overall design principle and major plans for reconstruction of the Shenhui Road．
Research conclusions:The using of the existing interchanges，the influence of the metro colineation and the reduction of demolition should be taken as the primary dominating factors for the overall design of this project． Combined with the change of the road function，the double － plate form should be used for the cross － sectional of the road． Based on making full use of the higher standard of the existing road，the plane line position should be designed flexibly． The filling and excavation heights of the vertical section should be controlled strictly to converge with the surrounding environment． Combined with perfecting of the surrounding road network，the function and service levels of the interchange should be determined reasonably，and the reconstruction of the interchanges should be optimized．
