Primary roads This class is sometimes called "National Roads or Highways". About 5% of the road network are primary roads. Primary roads are the most trafficked and most link neighbouring countries. One such road is the Zimbabwean portion of the Trans-African Highway as it passes through western Zimbabwe. This part of the road network plays a major role in the importation and exportation of the country's ware and transit freight. Among the primary roads some roads are classified as Regional Road Corridors, while some are just primary roads. Regional Road Corridors are numbered R1, R2, R3 and so on. They may also be called by their original type and route name like A1, A2, A3 etc. In some cases one type "R" road may be comprise two or more type "A" routes; e.g. R2 comprises A5 and A7 (Harare-Pluntree Road). Ordinary primary roads are numbered P1, P2, P3 etc. These are primary roads but not convenient for cross-border traffic and services.
