KoszalinShihrBhaderwah

In new street additions, Koszalin built increasingly disconnected streets over time, while Shihr fluctuated in its street-construction patterns and Bhaderwah built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Koszalin and Shihr both became progressively more disconnected, while Bhaderwah became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Koszalin had a more sprawly network than Shihr in 1975 but the two have since reversed their relative ranking.
