In new street additions, Jaén built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Cosenza built increasingly disconnected streets from 1975 through 1991-2005, then improved and Butajira built increasingly disconnected streets over time. Looking at the full network, Cosenza and Butajira both became progressively more disconnected, while Jaén grew more disconnected from 1975 through 1976-1990, then improved. Notably, Jaén had a more sprawly network than Butajira in 1975 but the two have since reversed their relative ranking.
