What about similarly populated cities?
In new street additions, Gu'an and Sanzhouyi both fluctuated in its street-construction patterns, while Bolpur built increasingly disconnected streets over time. For the full network, Gu'an grew more disconnected from 1975 through 1976-1990, then improved, while Sanzhouyi fluctuated in connectivity and Bolpur became progressively more disconnected. Gu'an and Bolpur have been converging in their street-network character since 1975.
