In new street additions, Qingan fluctuated in its street-construction patterns, while Mukubu built increasingly disconnected streets from 1975 through 1991-2005, then improved and Qingtian built increasingly disconnected streets over time. Looking at the full network, Mukubu and Qingtian both became progressively more disconnected, while Qingan fluctuated in connectivity. Notably, Qingan had a more sprawly network than Mukubu in 1975 but the two have since reversed their relative ranking.
