While Balqaş and Emişbeleni both built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, Qiubei built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full network, Qiubei grew more disconnected from 1975 through 1991-2005, then improved, while Balqaş became progressively more connected and Emişbeleni became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Qiubei had a more connected network than Balqaş in 1975 but the two have since reversed their relative ranking.
