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