In new street additions, Sukorejo built increasingly disconnected streets over time, while Spring Hill built increasingly disconnected streets from 1975 through 1991-2005, then improved and Congyuancun fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Sukorejo had a more sprawly network than Congyuancun in 1975 but the two have since reversed their relative ranking.
