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