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