Roads in Portugal

From Wikipedia, the free encyclopedia

The Plano Rodoviário Nacional (National Roadway Plan; PRN 2000) describes the existing and planned network of roads in Portugal. There are two types of routes in the plan: itinerários principais (IP; principal/main routes) and itinerários complementares (IC; complementary/secondary routes). Either type of route may be composed of several motorway/freeway/expressway type roads (i.e., grade-separated, controlled access roads, called auto-estradas in Portuguese) or regular roads (i.e., at-grade, non-controlled access roads) or a combination. Many roads will have more than one number simultaneously.

[edit] Auto-Estradas

 It has been suggested that Auto-estrada be merged into this article or section. (Discuss)

Auto-Estradas are roads which meet certain specifications. These roads are equivalent to motorways in many English-speaking countries and to expressways or freeways in the United States. Each Auto-Estradas forms part or all of an IP or an IC.[1] These are dedignated with an "A" code as well as an IP or an IC code, though they are typically known to motorists by the "A" designation. In addition, many of these roads are part of the European road network, and so also carry an "E" designation, which may serve as reference for non-Portuguese drivers.

[edit] Itinerários Principais

There are nine itinerários principais (IP; principal/main routes; singular: itinerário principal), designated IP 1 through IP 9.[2]

[edit] Itinerários Complementares

There are 37 itinerários complementares (IC; complementary/secondary routes; singular: itinerário complementar), designated IC 1 through IC 37.[3]

[edit] Estradas Nacionais

There are numerous estradas nacionais (EN; national roads; singular: estrada nacional), designated EN 1 through EN 398, with gaps in the numbers.[4] These are the ancient roads of the 1945 National Roadway Plan, which were not reclassified as IC or IP, but were kept in the national road network. In the 1945 Plan the number of the national road identified its class (EN 1 to EN 18 - Main Roads, EN 101 to EN 125 - 1st class, EN 201 to EN 270 - 2nd Class and EN 301 to EN 398 - 3rd class) but this system is now obsolete.

[edit] Estradas Regionais

There are numerous estradas regionais (ER; regional roads; singular: estrada regional), designated ER 1 through ER 396.[5] These are short roads serving a particular region. This type of road was introduced by the PRN 2000, by the transformation of former national roads. Each regional roads kept the number of the national road that has given origin to it (ex.: present ER 15 was the former EN 15).
