While Governador Valadares and Ikere-Ekiti both built increasingly disconnected streets over time, Saskatoon fluctuated in its street-construction patterns in new street additions. Looking at the full network, Governador Valadares and Ikere-Ekiti both became progressively more disconnected, while Saskatoon became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Saskatoon had a more sprawly network than Governador Valadares in 1975 but the two have since reversed their relative ranking.
