In new street additions, Poyang built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Kisaran built increasingly disconnected streets over time and Bern fluctuated in its street-construction patterns. Looking at the full network, Kisaran and Bern both became progressively more disconnected, while Poyang grew more disconnected from 1975 through 1976-1990, then improved. Poyang and Kisaran have been growing further apart in their street-network character since 1975.
