The BR-101 (also called Translitorânea, and officially named Rodovia Governador Mário Covas.) is a longitudinal highway of Brazil. It is the longest in the country with a length of nearly 4,800 km (3,000 mi), and it is considered the second most important.
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.
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).
It is a major Brazilian highway and part of the Pan-American Highway.
BR-101 is known as BRIOI..
The northern section between Curitiba and the border with São Paulo was not built in order to preserve an area of the Atlantic Forest.
The Rio-Niterói Bridge is part of the BR-101.
In 1973 the first stretch was widened between Rio de Janeiro-RJ and Cubatão-SP. In the 1980s the stretch between Cubatão-SP and Curitiba-PR was widened. In the 1990s the 312 km stretch between Curitiba-PR and Florianópolis-SC has been widened.
