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