Phases

For ease and co-ordination of developmental efforts, the city was divided into 'Phases' by its planners, with the city's development taking a concentric form with Phase 1, which consists of the city's inner districts-Central Area, Maitama, Asokoro, Wuse, Wuse II, Garki, Garki II, Guzape and Guzape II-at its core spreading out from the foot of Aso Rock, while Phase 5, consisting of the newly created Kyami District covering the vicinity of the Nnamdi Azikiwe International Airport and the permanent campus of the University of Abuja, over 40 kilometres west of Aso Rock. Each Phase is separated from the other by an expressway (some still under construction); for example, Phases 1 and 2 are separated from each other by the Nnamdi Azikiwe expressway, while the entirety of the city proper (Phases 1–5) are enclosed by the Murtala Muhammed (Outer Northern-ONEX and Outer Southern-OSEX) expressways as well as the Federal A2 highway which traverses the Federal Capital Territory on its way to Kaduna (north-bound) and Lokoja (south-bound). Thus, there is an integration of the city's road network with the Federal highway network, providing access to the immediate outlying countryside and the surrounding states of the country i.e. Niger State to the west, Kaduna State to the north, Nasarawa State to the east and Kogi State to the south.

Abuja is organised into phases, which are further divided into districts.
