Highways impact Communications and transportations by road are basic for the current society these days. Long distances connections have steadily improved due to the strategical construction of highways across the countries. Subsequently, this has a positive impact on time, travelling large distances, allowing us to save time. However, these huge infrastructures are associated with a variety of drawbacks that I will attempt to address in this essay. One of the most crucial consideration in this regard is the budget. Institutions usually are not acute enough calculating the constructions expenses of new roads, leading to the possibility that they become abandoned due to an increased final budget. In Spain, this problem arose the question related to the elaboration of construction strategies and plans, and whether they were precise enough. Maybe an external organization like the European Union could assess how acute are these strategies as a third party. It is necessary to take into consideration a relevant issue related to biodiversity. Some populations of animals are splited by the construction of highways through their environment, and it is undeniably true that this has a profound and negative impact on wild life and the related ecosystem. In consequence, this could lead to a balance alteration of the local environment. Governments and companies need to minimise this negative effect by building which are named “ecological paths”, to connect the wild life from the separated areas, either above or under the motorway. In conclusion, I mentioned above some relevant negatives points associated with the construction of highways. Institutions and Governments, along with the companies, need to elaborate plans including these strategies to tackle expenses related problems and trying to protect the environment of the area.
