In new street additions, Pouytenga built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Udalguri built increasingly disconnected streets over time and Guarapari fluctuated in its street-construction patterns. Looking at the full network, Udalguri and Guarapari both became progressively more disconnected, while Pouytenga became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Pouytenga had a more sprawly network than Guarapari in 1975 but the two have since reversed their relative ranking.
