While Heshan and Fungurume both built increasingly disconnected streets over time, Chimbote built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Chimbote and Heshan have been growing further apart in their street-network character since 1975.
