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