National Department of Transport Infrastructure
The National Department of Transport Infrastructure (Portuguese: Departamento Nacional de Infraestrutura de Transportes, DNIT) is a Brazilian federal agency linked to the Ministry of Transport that plans, builds, operates, and maintains elements of the Federal Transportation System (Sistema Federal de Viação). It was created by Law No. 10,233 of 5 June 2001 as part of a sectoral reorganisation that also extinguished the former National Department of Highways (Departamento Nacional de Estradas de Rodagem, DNER). DNIT is headquartered in Brasília, Federal District.[1][2] MandateUnder its legal mandate, DNIT implements federal policy for transport infrastructure under its care, including the operation, maintenance, rehabilitation, capacity upgrades, and expansion of federal highways, federal rail segments not under concession, and inland waterways and small public port facilities under federal jurisdiction. It also undertakes research, issues technical standards, coordinates with regulators and subnational authorities, and manages projects financed from the federal budget and other sources. Within federal highways, DNIT holds powers to enforce traffic rules and apply penalties through its weigh-station and roadway oversight programs.[3][4] Organization and legal basisLaw No. 10,233/2001 established DNIT as a public-law entity with administrative, budgetary, and financial autonomy, linked to the then Ministry of Transport (subsequently named the Ministry of Infrastructure from 2019 to 2022 and restored as the Ministry of Transport in 2023). The department's regimental structure and leadership posts are defined in federal decrees and internal regulations; the current regimental structure was approved by Decree No. 11,225 of 7 October 2022. DNIT's central administration is supported by technical directorates and by regional superintendencies in Brazil's states.[5][6][7][8] See alsoReferences
