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