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