While Ramadi and Colorado Springs both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Baishan built increasingly disconnected streets from 1975 through 1976-1990, then improved in new street additions. For the full street network, though, all three cities follow the same trend. Notably, Baishan had a more sprawly network than Ramadi in 1975 but the two have since reversed their relative ranking.
