In new street additions, Weining built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Amparihimahitsy built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Kislovodsk built increasingly disconnected streets over time. For the full network, Weining and Kislovodsk both became progressively more disconnected, while Amparihimahitsy grew more disconnected from 1975 through 1976-1990, then improved. Notably, Weining had a more connected network than Amparihimahitsy in 1975 but the two have since reversed their relative ranking.
