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