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