While Basildon and Yongfeng both built increasingly disconnected streets from 1975 through 1976-1990, then improved, Gelemso fluctuated in its street-construction patterns in new street additions. For the full network, Gelemso became progressively more disconnected, while Basildon grew more disconnected from 1975 through 1976-1990, then improved and Yongfeng grew more disconnected from 1975 through 1991-2005, then improved. Gelemso and Yongfeng have been converging in their street-network character since 1975.
