It is the longest in the country with a length of nearly 4800 km, and it is considered one of the most important highways in the country, along with BR-116.

It crosses 12 Brazilian states: Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul. It also connects more state capitals than any other "rodovia" (highway) in the country. In total, 12 capitals are directly connected by BR-101.

Its northern terminus is located in the city of Touros-RN and its southern terminus is located in São José do Norte-RS.

It follows virtually the entire east coast of Brazil from Rio Grande do Norte to Rio Grande do Sul. The highway has not been built between two stretches between Peruíbe (SP) and Iguape (SP), and between Cananéia (SP) and Garuva (SC).

Between Curitiba and Garuva (SC), the highway was replaced by the BR 101 / BR 376 and was widened by the Paraná government, not by the federal government.

The northern section between Curitiba and the border with São Paulo was not built to preserve an area of the Atlantic Forest.

The Rio-Niterói Bridge is part of the BR-101.
