While Lishui and Shenglicun both built increasingly disconnected streets over time, Kaolack built increasingly disconnected streets from 1975 through 1976-1990, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Kaolack and Lishui have been growing further apart in their street-network character since 1975.
