What about similarly populated cities?
Hexi, Deder, and Sandesh all built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street construction. For the full network, Hexi and Deder both grew more disconnected from 1975 through 1991-2005, then improved, while Sandesh became progressively more disconnected. Hexi and Sandesh have been converging in their street-network character since 1975.
