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