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