In new street additions, Dingzhou fluctuated in its street-construction patterns, while Urgench built increasingly disconnected streets from 1975 through 1991-2005, then improved and Yishui built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Dingzhou and Urgench have been converging in their street-network character since 1975.
