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