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