Study on the Creation of Landscape Environment for Beautiful Expressway Dynamic Corridor

Beautiful expressways are the traffic practice of the Beautiful China initiative. The visual environment of the highway is not only related to the quality of the highway landscape, but also provides crucial support for improving highway traffic safety. Considering the distinctive aspects of highway engineering and the remarkable attributes of the natural surroundings along the route, this paper proposes the implementation of tolerant subgrade design techniques that are finely tailored to the specific local conditions. These techniques involve the integration of excavation sites with leveled areas. Additionally, this paper suggests the implementation of meticulous adjustments in the micro-topography of roadside areas, interchange zones, service and parking areas, as well as management centers, with the aim of crafting scenic corridors. Furthermore, this paper recommends the restoration of slopes in a manner that closely resembles natural ecology, the safeguarding and transplantation of indigenous mature trees, and the creation of service facilities that exude a garden-like ambiance, thus establishing a linear and dynamic highway landscape corridor, brimming with distinctive local characteristics.
