Rada`GreeleyMeiganga

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