In new street additions, Bajil built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Mestre built increasingly disconnected streets from 1975 through 1991-2005, then improved and Shirpur fluctuated in its street-construction patterns. For the full network, Bajil became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Mestre became progressively more disconnected and Shirpur fluctuated in connectivity. Notably, Bajil had a more sprawly network than Shirpur in 1975 but the two have since reversed their relative ranking.
