While Facatativá and Daik-U both fluctuated in its street-construction patterns, Baoqing built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Baoqing and Facatativá have been growing further apart in their street-network character since 1975.
