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