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