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