# SADC Regional Trunk Road Network

The Southern African Development Community Regional Trunk Road Network or SADC RTRN is a trans nation road network across Southern Africa. The projects in Africa being developed by the United Nations Economic Commission for Africa (UNECA), the African Development Bank (ADB), and the African Union in conjunction with the Southern African Development Community. They aim to promote trade and alleviate poverty in Africa through highway infrastructure development and the management of road-based trade corridors.

## Background

The Southern African Development Community Regional Trunk Road Network (SADC RTRN) is a system of numbered roads in Southern Africa. The core of the network is the reference roads, which are major trans-regional routes. East-west oriented reference roads have a two-digit number with the second digit a 0. North-south oriented reference roads have a two-digit number with the second digit a 5. Intermediate roads connect two reference roads and also have two-digit numbers. Branch, link and connecting roads are less important routes, and are identified with a three-digit number.
