What about similarly populated cities?
In new street additions, Ede and Yima both built increasingly disconnected streets over time, while 新城子区 fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Ede had a more sprawly network than Yima in 1975 but the two have since reversed their relative ranking.
