In new street additions, Tartagal fluctuated in its street-construction patterns, while Binbei built increasingly disconnected streets from 1975 through 1976-1990, then improved and Schwerin built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Tartagal fluctuated in connectivity, while Binbei grew more disconnected from 1975 through 1976-1990, then improved and Schwerin became progressively more disconnected. Notably, Tartagal had a more sprawly network than Binbei in 1975 but the two have since reversed their relative ranking.
