Considering its location on the main highway leading to Abuja, the Mabushi interchange needed to be a feast for the eyes.

The design enables self-sufficiency so that the junction requires no maintenance whatsoever. The plans take advantage of the terrain's slopes to create water catchment systems which permit the four interchanges to self irrigate. Suitable plants were selected and raised on berms so as to make them visible to passing cars. The result is a vibrant, ever-changing landscape where plant life responds to the turning of the seasons.
