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