BR-101: Brazil's Essential East Coast Highway
The BR-101, officially known as the Rodovia Governador Mário Covas, is one of Brazil's most critical pieces of transportation infrastructure. Also referred to as the Translitorânea (transcoastal) or nicknamed Briói in certain regions, this longitudinal highway serves as the primary artery for the country's eastern coastline.
Spanning nearly 4,800 kilometers (approximately 3,000 miles), it is the second longest highway in Brazil. Its strategic importance is matched only by the BR-116, as it facilitates the movement of goods and people across a vast stretch of the Atlantic coast.

Key Facts
- Total Length: Approximately 4,658 miles (7,496.32 km).
- Scope: Crosses 12 Brazilian states.
- Connectivity: Connects more state capitals (12 in total) than any other highway in Brazil.
- Termini: Starts in Touros (Rio Grande do Norte) and ends in São José do Norte (Rio Grande do Sul).
- Major Landmark: Includes the famous Rio-Niterói Bridge.
Route and Geography
The BR-101 follows the east coast of Brazil, providing a vital link between the Northeast and the South. However, the route is not entirely continuous. There are two specific gaps where the highway was not constructed: between Peruíbe and Iguape in São Paulo, and between Cananéia (São Paulo) and Garuva (Santa Catarina).
In the region between Curitiba and Garuva, the route was replaced by a combination of BR-101 and BR-376, with widening projects managed by the state government of Paraná rather than federal authorities. Additionally, a northern section between Curitiba and the São Paulo border remains unbuilt to ensure the preservation of the Atlantic Forest, a critical biodiversity hotspot.

Infrastructure Development and Duplication
To accommodate increasing traffic, significant portions of the BR-101 have been converted into dual carriageways (divided highways with separate lanes for opposing traffic).
Southern and Southeast Regions
In the South, the 312 km stretch between Curitiba and Florianópolis was fully duplicated around 2000. A subsequent project between Palhoça and Osório began in 2005, with the final sections in Rio Grande do Sul and Santa Catarina opening by 2011 and 2019, respectively.
In the Southeast, the highway includes the 13 km Rio-Niterói Bridge and the 58 km Avenida Brasil in Rio de Janeiro. Between Rio Bonito and Campos dos Goytacazes, a 176.6 km stretch was awarded to the company Arteris in 2008, with significant duplication progress reported by 2018.

Northeast Region
Duplication efforts between Natal and Salvador began in 2005. While the section connecting Rio Grande do Norte, Paraíba, Pernambuco, and Alagoas is nearly complete, other areas face delays. In Sergipe, progress has been slower, with the Brazilian army managing certain works. In Bahia, duplication projects are planned from Feira de Santana to the Sergipe border and from Eunápolis to the Espírito Santo border, though completion dates remain unconfirmed.
