General description:
Motorways: 'A' numbers are used only for some short sections. Most motorways have a national (RN) number. All numbers begin with 0: the highest known number is A024. Since numbers are assigned sequentially, it seems unlikely that there will ever be more than 100 numbers so the first digit will always be zero. Some of the roads are single carriageways.
National roads: Numbers 1 - 14 denote main routes from/to Buenos Aires, increasing in counterclockwise direction. The RN40 is the main western north-south route. North of Mendoza it is the RN40N, south of Mendoza it is the RN40S (these suffixes were introduced recently).
Special numbers are RN1V09 (which is a motorway parallel to RN9) and RN1V07 (near RN7). Also, RNV66 branches off RN66.
Provincial roads: Most provinces have 1- and 2-digit numbers and some also have 3-digit numbers (these are usually less important but there are exceptions, see region table. The province Tierra del Fuego, Antartida e Islas del Atlantico Sur does not have provincial roads. Instead, there are special national roads with numbers beginning with 24C and a letter A-K. Formerly, these were numbered just lowercase a-k (e.g. RNb was replaced by RN24CB).
Road signs: Blue with white text. Road number shields white with black text. Shape for national numbers: pentagon (as in Hungary), for provincial numbers: rectangle.
History: National road numbers were introduced in 1932. Most of them have never been changed.
Provincial roads have been changed in some provinces:
