In new street additions, Mongu fluctuated in its street-construction patterns, while Kanhangad built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Corumbá built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Mongu grew more disconnected from 1975 through 1976-1990, then improved, while Kanhangad became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Corumbá grew more disconnected from 1975 through 1991-2005, then improved. Notably, Mongu had a more sprawly network than Corumbá in 1975 but the two have since reversed their relative ranking.
