In new street additions, 赵家沟 fluctuated in its street-construction patterns, while Woldia built increasingly disconnected streets over time and Como built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. 赵家沟 and Como have been growing further apart in their street-network character since 1975.
