The proposal aims to reorganize the lateral green zones of DN1 to protect both vegetation and pedestrian circulation. The planted area is raised above the roadway level to limit splashing, snow deposits, and the impact of deicing substances. Tall vegetation is arranged in sequences of three different species, creating a dynamic visual rhythm suited to a high traffic route, while the base is complemented with medium and small plants that filter air and screen the pedestrian zone. Where width permits, the green space is expanded with shrub masses, using exclusively pollution resistant species with low maintenance requirements.
