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