In new street additions, Ramadi built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Resistencia fluctuated in its street-construction patterns and Baishan built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. Notably, Ramadi had a more connected network than Baishan in 1975 but the two have since reversed their relative ranking.
