In new street additions, Obe built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Shiren built increasingly disconnected streets from 1975 through 1991-2005, then improved and Jingguan fluctuated in its street-construction patterns. For the full network, Obe became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Shiren became progressively more disconnected and Jingguan fluctuated in connectivity. Notably, Obe had a more sprawly network than Shiren in 1975 but the two have since reversed their relative ranking.
