Restricted by the terrain,the layout of interchanges and service areas of mountainous highways are complex.In terms of functional requirements and engineering investment,it is considered that merging the interchange with the service area.Based on the merging design of Gaoping Interchange and Gaoping Service Area in a mountainous highway in Hunan Province,this paper discussed the merging schemes according to the topographic and geological conditions,traffic flow direction,existing road network,village distribution,and other situations,and determined an optimal design scheme,which can provide a reference for similar engineering projects.
