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