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