What about similarly populated cities?
In new street additions, Mengshan built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Salha fluctuated in its street-construction patterns and Opobo fluctuated in its street-construction patterns. For the full network, Mengshan grew more disconnected from 1975 through 1991-2005, then improved, while Salha grew more disconnected from 1975 through 1976-1990, then improved and Opobo became progressively more disconnected. Mengshan and Salha have been converging in their street-network character since 1975.
