While Sherbrooke and Dongxing both built increasingly disconnected streets over time, Linköping built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Linköping and Sherbrooke have been growing further apart in their street-network character since 1975.
