What about similarly populated cities?
Middlesbrough, Chandausi, and Jacksonville all built increasingly disconnected streets over time in new street construction. The same pattern holds for the full street network. Notably, Middlesbrough had a more sprawly network than Jacksonville in 1975 but the two have since reversed their relative ranking.
