Primary road network comprises north–south axis (M1), inner ring road, outer ring road, Nacala corridor (part of the western bypass), radial roads and the Kamuzu International Airport (KIA) access road. The inner ring road connects with M1 and other main roads serving the high accumulated commercial/administration areas in the central business districts (CBD). The outer ring road serves industry-related traffic and avoids passing through the main built-up area of the city.
