This article combines the planning and design of Chengdu intercity expressway,analyzes its functional positioning and road level,and focuses on exploring the design principles of intercity expressway route intersections.Through reasearch,it is known that,when intercity expressway intersects with expressway,first-class highway and important trunk highway,or intersects with expressway,trunk road and secondary trunk road with large traffic volume in urban planning area,interchange should be set;When intersecting with other levels of highways,except for interchanges due to traffic conversion,separate interchanges must be set up;When intersecting with low-grade roads within the urban planning area,auxiliary road level crossings can be used when there is a need for traffic conversion.
