Abstract
Brazil is in a situation of marked degradation in the road system, both in the sense of lacking new road projects and needing repairs to its current infrastructure. It is known that with the demographic increase over the years several positive and negative environmental impacts were caused and that the highways are works that generate great environmental impact. An environmental impact is defined as any change caused to the environment by humans, in turn the negative leads to an ecological imbalance, causing serious damage to the environment. In addition to the great polluting effects of the gases released by car exhaust, there is also the impact of road construction, which implies the withdrawal and transfer of huge amounts of land, deforestation, changes in the form of water runoff, silting of rivers and associated urban expansion. The purpose of this article is to analyze the fundamentals that support the concept, understand the challenges posed and the level of adequacy that reveal the need for legitimacy of the article.
