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