What about similarly populated cities?
While Sarapul and Cosenza both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Shuifu built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns in new street additions. Looking at the full network, Sarapul and Cosenza both became progressively more disconnected, while Shuifu became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards.
