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