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