List of federal highways in Brazil
From Wikipedia, the free encyclopedia
This is a list of the federal highways in Brazil. The current numbering system has existed since 1964, with changes in 1973.[1][2][3]
Brazilian federal road names are composed of the ISO 3166 code "BR", a dash and three numbers. State highways in the country are classified as YY-XXX, where YY is the abbreviation of the state where the highway is located and XXX is a number. The first digit in the number determines which of the five categories the National Road System divides it into.
