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