Trans-Amazonian Highway

The highway was intended to integrate these regions with the rest of the country, and with Peru and Ecuador. It was originally planned to be a fully paved highway 5200 kilometers long. However, these plans were modified following its inauguration.
In particular, because of high construction costs and Brazil financial crisis in the late 1970s, only a part of the highway was paved, from its beginning to 200 km ahead of Marabá. The lack of a fully sealed road causes many problems. Travel on the non-paved stretches of the highway is extremely difficult during the region's rainy season between October and March. In the wet season cars often get stuck in the poorly constructed road and in the dry season there are often pot holes in the dry mud roads that damage vehicles.
