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