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