In new street additions, Nanba built increasingly disconnected streets from 1975 through 1991-2005, then improved, while New Tafo Akim built increasingly disconnected streets over time and Itumbiara fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Nanba had a more sprawly network than New Tafo Akim in 1975 but the two have since reversed their relative ranking.
