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