In new street additions, Takaba built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Hildesheim built increasingly disconnected streets from 1975 through 1991-2005, then improved and Fazenda Rio Grande built increasingly disconnected streets over time. Looking at the full network, Hildesheim and Fazenda Rio Grande both became progressively more disconnected, while Takaba became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Takaba had a more sprawly network than Fazenda Rio Grande in 1975 but the two have since reversed their relative ranking.
