In new street additions, Yulin built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Khabarovsk built increasingly disconnected streets from 1975 through 1991-2005, then improved and Novo Hamburgo built increasingly disconnected streets over time. Looking at the full network, Khabarovsk and Novo Hamburgo both became progressively more disconnected, while Yulin became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Yulin had a more sprawly network than Khabarovsk in 1975 but the two have since reversed their relative ranking.
