While Al Qaramus and Awomama both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Ifetedo built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns in new street additions. Looking at the full network, Al Qaramus and Awomama both became progressively more disconnected, while Ifetedo became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Ifetedo had a more connected network than Al Qaramus in 1975 but the two have since reversed their relative ranking.
