What about similarly populated cities?
In new street additions, Girza fluctuated in its street-construction patterns, while Golmorti built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Biliri built increasingly disconnected streets over time. For the full network, Girza became progressively more connected, while Golmorti became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Biliri became progressively more disconnected. Girza and Biliri have been converging in their street-network character since 1975.
