What about similarly populated cities?
In new street additions, Biala and Azov both built increasingly disconnected streets over time, while Dunedin built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Biala and Dunedin have been growing further apart in their street-network character since 1975.
