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