In new street additions, Jinzhou and Cartagena both fluctuated in its street-construction patterns, while Mataram built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Notably, Jinzhou had a more sprawly network than Cartagena in 1975 but the two have since reversed their relative ranking.
