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