In new street additions, Hongya fluctuated in its street-construction patterns, while Norristown built increasingly disconnected streets from 1975 through 1991-2005, then improved and An Numaniyah built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Hongya and Norristown both became progressively more disconnected, while An Numaniyah became progressively more connected. Notably, Hongya had a more connected network than An Numaniyah in 1975 but the two have since reversed their relative ranking.
