President Martín Vizcarra's government will invest millions of dollars in road improvements in Lima's sister port city of Callao ahead of next year's Pan American Games.
Unit 7 of the Villavicencio-Yopal corridor involves improving an existing 25.7km stretch and building a second lane along that section, among other tasks.
The Brazilian construction group agreed to pay a fine of nearly US$400mn.
The investment arm of Brazilian development bank BNDES will invest in a total of eight funds.
The organization's fund FOCEM will provide US$93mn for the US$156mn project, which involves works on 123km of roads.
The company also said it is preparing to return to the port sector.
