In new street additions, Daqing built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Bhind built increasingly disconnected streets over time and Oita fluctuated in its street-construction patterns. Looking at the full network, Bhind and Oita both became progressively more disconnected, while Daqing became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Daqing and Bhind have been growing further apart in their street-network character since 1975.
