In new street additions, Huairen fluctuated in its street-construction patterns, while Songea built increasingly disconnected streets over time and Yanggu built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Huairen grew more disconnected from 1975 through 1976-1990, then improved, while Songea became progressively more disconnected and Yanggu became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Huairen and Songea have been converging in their street-network character since 1975.
