Xin Hua Cun BarrancabermejaAd-Damazin

In new street additions, 新华村 built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Barrancabermeja fluctuated in its street-construction patterns and Ad-Damazin built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Barrancabermeja and Ad-Damazin both became progressively more disconnected, while 新华村 became progressively more connected. Notably, 新华村 had a more sprawly network than Barrancabermeja in 1975 but the two have since reversed their relative ranking.
