In new street additions, Jinka built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Gaizhou fluctuated in its street-construction patterns and Regina built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Jinka became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Gaizhou grew more disconnected from 1975 through 1976-1990, then improved and Regina became progressively more disconnected. Jinka and Gaizhou have been converging in their street-network character since 1975.
