DNIT

DNIT, or Departamento Nacional de Infraestrutura de Transportes, is a Brazilian federal government agency linked to the Ministry of Infrastructure. Its core responsibility is the planning, execution, and maintenance of Brazil's national transport infrastructure, with primary emphasis on the federal highway network.

The agency carries out a range of activities essential to transport systems. These include studying and designing road projects, supervising bidding and contracting, and overseeing the construction and ongoing maintenance of federal highways. DNIT also manages pavement and bridge safety programs, sets technical standards for roads, signs, and markings, and coordinates with other levels of government to ensure compatibility across the National Transport System. In addition, it participates in environmental licensing, safety initiatives, and emergency response relating to transport infrastructure.

DNIT operates through regional superintendencies and technical divisions that provide planning, engineering, procurement, and oversight. It works in collaboration with state and municipal authorities and with private operators on public works and concession arrangements for road segments. While its primary focus is road infrastructure, the agency also coordinates with other transport sectors as part of Brazil’s integrated transport policy.

Overall, DNIT aims to deliver safe, efficient, and sustainable transport infrastructure across the federal network, supporting regional development and national mobility. The agency functions as a key implementing body within the broader framework of Brazil’s infrastructure governance.
