Amapá is characterized with the highest percentage of its land used for conservation, housing national parks, biological reserves, national forests, ecological stations and areas of environmental protection. The BR-156 highway along the entire state of Amapá, where many streams and drainage cuts, which have connection with the Coastal Plain. It is through this highway, which provides transportation fuels, with a higher frequency as the threat of accidents on the path and, consequently, affecting nearby ecosystems. This work aims to generally identify critical areas for the transport of fuel on the highway BR-156, based on the use of a methodology for interpretation of remote sensing and field recognition, integrated mapping of landscape units with data systems Geographic Information System (GIS). It was made the map of environmental vulnerability in the around of the highway BR-156, as well as identifying the major drainages, combined with the observations of the surrounding land use and settlement along the road. It was found the most of the area is classified into the category of very low environmental vulnerability, and low to medium. The results of the environmental vulnerability map of the around of the highway, the areas that were most prominent were the around of the road, performing urban settlement, associated, also, the areas of Training Barriers and fluvial marine and fluvial lacustrine plains. The study showed that the results obtained, together with the significant cut in highway drainage, combined with a absence of highway infrastructure in good condition are important factors contributing to classify that area as critical to transportation fuels.
