In new street additions, Lianjiang and Shenqiu both built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Rumbek built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Lianjiang became progressively more disconnected, while Shenqiu grew more disconnected from 1975 through 1991-2005, then improved and Rumbek became progressively more connected. Notably, Lianjiang had a more connected network than Rumbek in 1975 but the two have since reversed their relative ranking.
