What about similarly populated cities?
In new street additions, Lianyuan and Abakan both fluctuated in its street-construction patterns, while Jingbian built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Lianyuan grew more disconnected from 1975 through 1976-1990, then improved, while Jingbian became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Abakan became progressively more disconnected. Lianyuan and Jingbian have been converging in their street-network character since 1975.
