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