While Nuevo Casas Grandes and Colônia de Férias Ministro João Cleófas both fluctuated in its street-construction patterns, Taher built increasingly disconnected streets from 1975 through 1976-1990, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Taher and Colônia de Férias Ministro João Cleófas have been growing further apart in their street-network character since 1975.
