In new street additions, Redenção built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Dhlail built increasingly connected streets over time and Cáceres fluctuated in its street-construction patterns. For the full network, Redenção and Cáceres both became progressively more disconnected, while Dhlail became progressively more connected. Notably, Redenção had a more sprawly network than Cáceres in 1975 but the two have since reversed their relative ranking.
