In new street additions, Qixia built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Makou built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Gobesa built increasingly disconnected streets over time. For the full network, Qixia and Gobesa both became progressively more disconnected, while Makou became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Qixia and Makou have been growing further apart in their street-network character since 1975.
