What about similarly populated cities?
In new street additions, Jinxian built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Colón built increasingly disconnected streets over time and Ostrava fluctuated in its street-construction patterns. Looking at the full network, Colón and Ostrava both became progressively more disconnected, while Jinxian grew more disconnected from 1975 through 1976-1990, then improved. Jinxian and Colón have been growing further apart in their street-network character since 1975.
