BR-163
BR-163 is a highway in Brazil, going from Tenente Portela, at Rio Grande do Sul state, to Santarém in the state of Pará (the stretch between Santarem and Brazil-Suriname border has some deployed stretches, but all dirt paved, and there is no direct link due to the lack of a bridge over the Amazon River, only going by ferry crossing). The total length of the road is 4,476 km (2,781 mi),[1] a part in the heart of the Amazon Basin.[2] The road has almost 1,000 km, all in the state of Pará (at Amazon rainforest), not asphalted. As part of the Avança Brasil project, it has been proposed to pave the road in its entirety.
