In new street additions, Sari and Tapachula both built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Sevastopol built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. Sari and Sevastopol have been growing further apart in their street-network character since 1975.
