Dirección Nacional de Vialidad

Dirección Nacional de Vialidad (also called Vialidad Nacional; English: National Directorate of Roads), is an Argentine government agency controlled by the Secretariat of Transport. Its mission is to project, build, maintain, improve and expand the road transport network in Argentina. In the case of executing extensions, the DNV has powers to declare the land corresponding to the road as public utility, which enabled the beginning of expropriation trials. The DNV had 2,802 employees in 2006. At the moment of the announce of its dissolution in 2025, the plant had increased to 5,184, of which 67% fulfilled administrative functions and 33% were in charge of operational functions.

The dissolution of the agency had been announced by the Government of Argentina in a press conference and officialised one day later through decree n° 461/2025. Nevertheless, On July 17, 2025, the court of General San Martín Partido gave rise to a precautionary presented, suspending the dissolution. The government appealed the ruling.

Decree 461 was then rejected by the Argentine National Congress so Vialidad continued operating.
