In new street additions, Altay fluctuated in its street-construction patterns, while Shiroro built increasingly disconnected streets over time and Udharbond built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Shiroro and Udharbond both became progressively more disconnected, while Altay became progressively more connected. Notably, Altay had a more sprawly network than Udharbond in 1975 but the two have since reversed their relative ranking.
