What about similarly populated cities?
In new street additions, Edmonton built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Mingora built increasingly disconnected streets over time and Dharwad built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Edmonton and Mingora both became progressively more disconnected, while Dharwad became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards.
