What about similarly populated cities?
In new street additions, Asamankese and Srivilliputtur both built increasingly disconnected streets over time, while Erzincan fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Asamankese and Erzincan have been growing further apart in their street-network character since 1975.
