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