It covers a total distance of 402 kilometres (250 mi), starting at the Trevo das Margaridas in Rio de Janeiro and ending at the junction with Marginal Tietê in São Paulo. It merges with Rodovia Ayrton Senna in the county of Guararema and has junctions with the Rodovia Fernão Dias, the BR-354 and the BR-459. The highway largely follows the Paraíba do Sul river valley.
The Via Dutra is considered the most important Brazilian highway since it connects the two biggest and most important cities of Brazil and runs through one of the richest regions of the country, the Paraíba Valley. It is also the most important connection between the Southern Region and the Northeast Region. It is named after former Brazilian president Eurico Gaspar Dutra, who inaugurated the highway.
At the end of the 1940s industrialization and the necessity of a faster, safer and more efficient and modern road connection of the two biggest Brazilian cities led to the construction of the Rodovia Presidente Dutra as it is known today. It was inaugurated on Friday, 19 January 1951, by the President Eurico Gaspar Dutra and called BR-2. It was a two-lane road with exception of the stretches between São Paulo and Guarulhos and in the Baixada Fluminense where it was a four-lane dual carriageway.
In the 1960s it had various stretches converted to four-lane divided road. In 1967 it was fully converted to four-lane highway status.
The highway is managed and maintained by a state concession to the private company NovaDutra S/A since March 1996, and therefore is a toll road. From that transfer of ownership up to today it has largely improved in road quality and safety.
