In new street additions, Frankfurt built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Donetsk built increasingly disconnected streets from 1975 through 1991-2005, then improved and Bikaner fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Frankfurt and Bikaner have been growing further apart in their street-network character since 1975.
