it means that the highway runs in a south–north way 200-299 - it means that the highway runs in a west–east way 300-399 - it means that the highway runs in a diagonal way. Highways with odd numbers run northeast–southwest, while even numbers run northwest–southeast. 400-499 - it means that the highway interconnects two major highways. 600-699 - it is a special designation given to highways of national importance but that just interconnect a highway to an important location. There currently are only two such highways in the country, BR-600 which connects the Itaipu Dam to BR-277 and BR-610 which connects the Guarulhos International Airport to BR-116 and SP-070. Often Brazilian highways receive names (famous people, etc.), but continue to have a YY/BR-XXX name (example: Rodovia Castelo Branco is also SP-280). See highway system of São Paulo for numbering designation for São Paulo state roads, also used in some other states.

It has the official name of Rodovia Bernardo Sayão (the name of its chief engineer, who died in an accident during the construction of the highway, when a tree fell on him), and is also called Belém–Brasília Highway or as Transbrasiliana Highway, in the stretch between the city of Estreito, in the state of Maranhão, and the city of Belém. This is due to the fact that between Brasília and Estreito, the highway has many incomplete and unpaved stretches, especially in the state of Tocantins.

The BR-010 passes through the Federal District, and the states of Goiás, Tocantins, Maranhão and Pará. BR-020 The BR-020 connects Fortaleza in Ceará to the federal capital Brasília. Like other BRs that start with the number 0, it leaves Brasília to an extreme point in Brazil.
