What about similarly populated cities?
In new street additions, Ulanqab built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Centurion built increasingly disconnected streets from 1975 through 1991-2005, then improved and Xuancheng built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Ulanqab grew more disconnected from 1975 through 1976-1990, then improved, while Centurion became progressively more disconnected and Xuancheng became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Ulanqab had a more sprawly network than Xuancheng in 1975 but the two have since reversed their relative ranking.
