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