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