In new street additions, Jiangyin fluctuated in its street-construction patterns, while Lipa built increasingly disconnected streets from 1975 through 1991-2005, then improved and Londrina built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Jiangyin and Lipa have been growing further apart in their street-network character since 1975.
