Route description
BR-116 runs in a north-south direction, close to, but not on Brazil's coastline. It is the second longest highway in the country and, by connecting major urban centers including Fortaleza, São Paulo, Rio de Janeiro, Curitiba and Porto Alegre, arguably the most important and busiest Brazilian highway. Numerous stretches of BR-116 highway have other official names.

The highway is especially busy along the Curitiba—São Paulo—Rio de Janeiro section. The Curitiba–São Paulo section–officially known as the Régis Bittencourt Highway (Rodovia Régis Bittencourt)–is nicknamed the "Highway of Death" ("Rodovia da Morte") due to its many weather-related accidents. The São Paulo—Rio de Janeiro section is officially named President Dutra Highway (Rodovia Presidente Dutra) and is the busiest section of BR-116, running into or close to 15 cities with over 200,000 inhabitants. The section between Novo Hamburgo and Porto Alegre is also heavily trafficked, and there is a strong movement of cargo between Porto Alegre and the Port of Rio Grande, in Pelotas.

Major cities directly served by BR-116 highway are: Fortaleza, Salgueiro, Feira de Santana, Vitória da Conquista, Teófilo Otoni, Governador Valadares, Rio de Janeiro, Volta Redonda, São José dos Campos, São Paulo, Curitiba, Lages, Caxias do Sul, Canoas, Porto Alegre, Pelotas.
