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