While Salka and Akhorwal both built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, Hejie fluctuated in its street-construction patterns in new street additions. For the full network, Hejie fluctuated in connectivity, while Salka became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Akhorwal became progressively more connected. Hejie and Salka have been growing further apart in their street-network character since 1975.
