Road infrastructure can be beautiful too. NEPA's emphasis on the overall environment has expanded the context of project aesthetics. The examination of the aesthetic resource element requires consideration of each of the following:
Internal Aesthetics - Follows traditional visual design theory to look at a project as a self-contained object, apart from its surroundings.
Relational Aesthetics - Considers the visual relationships between a project and specific elements of its surroundings; can be very important in community acceptance of a project.
Environmental Aesthetics - Examines aesthetics of the total affected environment; closely related to Scenic.
