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