In new street additions, Chodavaram built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Santa Rosa built increasingly disconnected streets over time and Fernandópolis fluctuated in its street-construction patterns. Looking at the full network, Santa Rosa and Fernandópolis both became progressively more disconnected, while Chodavaram became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Chodavaram had a more sprawly network than Santa Rosa in 1975 but the two have since reversed their relative ranking.
