With　the　integrated　development　of　transportation　and　tourism,　building　tourism　highways　has　become　a　new　direction　leading　the　transportation　industry　and　also　an　important　sector　of　green　transportation.　Currently,　the　planning,　design　and　construction　of　tourism　highways　in　China　are　at　their　early　stage,　and　there　are　few　relevant　codes,　specifications,　and　standards　concerning　the　planning　and　design.　This　paper　introduces　the　connotation　of　Tourism　Highways,　and　clarifies　the　scope　and　principles　of　the　planning　and　design.　It　puts　forward　the　planning　and　design　concept　of　coastal　tourism　highways,　and　carries　out　planning　and　design　practices　for　coastal　highways　in　Guangdong　based　on　the　concept.　©　The　Authors,　published　by　EDP　Sciences,　2020.
