[1] The highway has high economic importance for Brazil and even for Paraguay, as it connects the Brazil-Paraguay border with Port of Paranaguá.

BR-277, as well as BRs 369 and 376, which form a triangle within the state of Paraná, were granted to private companies in 1997, at the beginning of the era of road concessions in Brazil.

Initially, 995 km of roads in Paraná should be duplicated, and the population was promised that the State would have First World highways, strongly boosting economic growth.

The MPF (Federal Public Ministry) then carried out Operation Integration, which showed that the changes made to the contracts are part of a millionaire kickback scheme.

[7] For the next concession, to take place in 2021, the Federal Government, under the command of Jair Bolsonaro, and the Government of the State of Paraná, under the command of Ratinho Júnior, intend, together, adopt a model with lower tariffs, ensure that duplications occur quickly, and also ensure transparency in spending.
